EG Auto Add to Cart Free Gift, from the developer 506, automatically adds a free gift or promotional product to the cart when a shopper meets a rule you set: a cart subtotal, a specific product, a collection or a customer tag. It runs gift-with-purchase, BOGO and buy-X-get-Y offers without making the shopper enter a discount code. It holds a 4.9/5 rating from 1,126 on the Shopify App Store, and in our detection data it runs on 2.3% of the 3.5M+ Shopify stores we track.

The verdict upfront: EG Auto Add to Cart is a strong pick for a store that leans on promotions to lift average order value, because removing the coupon step removes the point where a lot of gift offers lose the shopper. Its rule targeting is deep enough to match an offer to a segment rather than the whole store. The honest limit is that auto-adding a gift leans on your theme’s cart, so test that the reward shows and removes cleanly before a campaign, and the entry plan caps active rules, so a store running many concurrent promos will need a higher tier.

What is EG Auto Add to Cart?

EG Auto Add to Cart Free Gift is an app from 506 that automates promotional add-ons. You set a rule, and when a shopper meets it the app drops the reward straight into the cart, or shows a popup to let the shopper pick, without a discount code. Rules can key off cart subtotal, quantity, a specific product, a collection or a customer tag, and you can schedule offers to start and stop on set dates. It is built for the promotions stores actually run: gift-with-purchase, BOGO, buy-X-get-Y and free-shipping-style thresholds.

It is free to start with a single live rule, enough to test whether auto-added gifts move your average order value before paying. Paid tiers raise the number of active rules and add deeper targeting and analytics. Here is how widely EG Auto Add to Cart is detected across Shopify.

How popular is EG Auto Add to Cart on Shopify?

EG Auto Add to Cart runs on 2.3% of the Shopify stores in our dataset, which places it among the most-used cart apps we track. Auto-gift apps are a considered install for stores that run promotions, so a footprint that size means a lot of owners decided the coupon step was costing them conversions and moved the reward into the cart automatically.

The rating backs that up. EG Auto Add to Cart holds a 4.9/5 score from 1,126, one of the higher marks in the cart category, with merchants crediting the automation with real average-order-value lifts. A high rating on a large review base is a stronger signal than a perfect score on a handful.

What does EG Auto Add to Cart do?

EG Auto Add to Cart runs promotional rewards on autopilot. The main pieces:

  • Trigger rules. Fire an offer on cart subtotal, quantity, specific products, collections or tags.
  • Auto-add or popup. Drop the reward straight into the cart, or show a popup so the shopper chooses.
  • Offer types. Gift-with-purchase, BOGO, buy-X-get-Y and threshold rewards, all without a discount code.
  • Scheduling. Set start and end dates so a campaign runs and stops on its own.
  • Customer targeting. Match offers by customer tag, order history, spend or B2B status.
  • Analytics. Per-rule order reporting with CSV export to see which offers actually pay.

The common thread is removing friction from promotions. The reward appears at the right moment without the shopper doing anything, which is the whole reason auto-add converts better than a code they have to remember.

What EG Auto Add to Cart costs on Shopify

EG Auto Add to Cart’s pricing on the Shopify App Store runs Free, or from $14.99/mo, starting with a free plan that covers a single live rule and stepping up to paid tiers that add more concurrent rules, deeper targeting and analytics. A store testing one gift-with-purchase offer can stay free; a store running several promotions at once will need a higher tier. Start free with one rule, confirm the reward adds and removes cleanly on your theme, then scale up when you run more offers.

Is EG Auto Add to Cart worth it?

For a store that leans on promotions, yes. Gift-with-purchase and BOGO offers convert far better when the reward adds itself than when a shopper has to find and enter a code, and the rule targeting means you can match an offer to a segment instead of blasting the whole store. Because a single rule is free, testing whether auto-added gifts lift your average order value costs nothing upfront.

Where it gives back less is a store that rarely runs promotions, where the automation has little to do. There is also a practical check: auto-adding leans on your theme’s cart, so a reward can behave oddly on a heavily customized cart. Test that gifts add and remove cleanly before a campaign, and mind the entry plan’s rule cap if you run many offers at once. On a promotion-driven store, it is worth it.

Which themes run with EG Auto Add to Cart?

What kinds of stores use EG Auto Add to Cart?

EG Auto Add to Cart stores skew toward subscription and multichannel selling, the profile of stores that run frequent offers and reward repeat buyers. These are stores that treat promotions as a regular lever, not a one-off, which is exactly where auto-added gifts pay back.

The app stack makes the pattern obvious. Nearly four in five of these stores also run Klaviyo, and they pair it with Judge.me, Loox and Yotpo at high rates, the email and reviews tools of stores actively working on conversion and retention. EG Auto Add to Cart sits inside that stack as the piece that runs the promotions the email tools announce.

EG Auto Add to Cart vs the alternatives

The cart and upsell category runs from full personalization engines to focused promotion tools, and EG Auto Add to Cart sits at the focused end: it does automated gifts and rewards well rather than trying to be the whole cart. Kaching Cart is the broader slide-cart option if you also want upsells and a free-shipping bar in the drawer, Rebuy is the heavier personalization engine for AI-picked recommendations, and ReConvert works the post-purchase page instead of the cart.

Real-world Core Web Vitals from the Chrome UX Report, matched to the apps we detect on the same stores. The unmatched row is shown for contrast only. It compares two different kinds of store, which is why the like-for-like row is the one to read. These are associations, not causes: stores running long app lists are bigger and busier than stores running short ones, so an app marks the kind of store as much as it moves the numbers. Store counts are shown on every row. How we measure.

Who should use EG Auto Add to Cart?

Reach for EG Auto Add to Cart if promotions are a regular part of how you sell: gift-with-purchase, BOGO, or spend-threshold rewards. The free single-rule tier is the right way to test whether auto-added gifts lift your average order value, and the paid tiers make sense once you are running several offers at once and want the targeting and analytics.

Think twice if you rarely run offers, where the automation has little to work with, or if you want a full cart drawer with upsells and a shipping bar, which is a broader tool’s job. EG Auto Add to Cart is the promotions engine; pair it with the cart and email tools that carry the rest.

Removing the coupon step lifts conversion on gift offers, the rule targeting is genuinely deep, and the free tier lets you prove it before paying. Just test that gifts add and remove cleanly on your theme’s cart, and mind the rule cap on the entry plan.
