Cross Sell & Upsell by SSC

I cannot recommend this App highly enough. I sell swimwear and really needed to show briefs with bikini tops. Shopify's random recommended products were nonsensical on the page - showing more bikini tops next to bikinis. I tried two other Apps but they didn't work with my template and based on my experience, they can't achieve customised product by product cross sells.
This App really works and it's easy to change the font sizes and colours.
The support was excellent too. I got an answer to a question immediately over the weekend.
If you want to see how it looks feel free to check some swimwear on my website www.airymary.com
Also, if you put something in the cart you'll see the 'Before you checkout have you considered.....?' recommended products which always show up (generic products I'm keen to upsell).
Do persevere if you've had trouble with other Apps. This one is worth it.

Fan-tastic! Great app, reasonable price and amazing service.
Stuart contacted me shortly after we installed our app and offered to customize the look and feel to fit our site. How cool is that?
Plus, they went above and beyond the call of duty and created some new logic for us so that if a product was in the cart then it wouldn't display as a cross sell product.
Highly recommended app.

D'Angelo is always quick to reply and helps us resolve any issues with how the app displays on the website. Highly recommend!

Great responsive support. Easy to set up. Having run my store for a number of years on a different platform, I can see this is a very powerful tool. It easily does what used to be a very labour-intensive process for me. I am wrapped! $ well spent!

This app does exactly what it's supposed to do, and I have no complaints. I specifically am happy about their support. We requested customizations (adding Product Name + Price copy under the cross-sell products at checkout), and their support team responded in less than an hour and was able to help make the updates. They also proactively offered to make other functionality upgrades based on new offerings. We've been very happy with the Cross-Sell app and I would highly recommend.

This is an amazing app and was even offered a customization so the cross-sell products fit the design of my website! Great thanks to Stuart and his team! Highly recommended!

Cross Sell is simple to use -- you'll be up-and-running in minutes. Just download the app and their team of developers will even take care of installation for you! The interface is plug-and-play and very intuitive. The developer was also extremely responsive via email and listened to a couple product features that they're putting on their future roadmap. Five stars for Cross-Sell!

We have had Cross Sell running for around 3 years now. It is an app that we definitely cannot do without. Spending time and putting thought into relating products is well worthwhile, resulting in extra sales, and helps quite often to lift our average order value.

Great app and easy to use! Stuart was so helpful in cleaning up the look of Cross-Sell and customizing it to my theme (Venture). I think it will really help customers find other products they might like easily and efficiently. Definitely worth the $7/month!

Amazingly easy app to install and impeccable assistance from the help team to customise for our store completely free! We received a response for our help request within half an hour of sending an email. Absolutely recommendable.
