Easily the #1 app you need on your store. Desktop and responsive. Facilitates conversion on anything you're driving in your funnel. Super easy to implement too .... and super easy to change on the fly.

Great app for pairing logical items together to increase sales. James, a mainstay in the bold leadership, put this one on my radar. I've used a moderately customized theme for a couple years and BOLD is the only shop I let touch my code. I use their apps and I use their developers to get things updated and working tight together. James runs a top notch team with continuity and current webdev skills - two things that are hard to find.

There is no better way to get the job done for discounting items. Plus this is a must have if you're using product upsell. Makes things super easy to schedule and easily rotate items in and out of offers with a few easy clicks. Bold was even smart enough to allow for tagging of discounted items so they can automagically show up in shopify smart collections for some advanced usage scenarios.

Upsell, along with discount and a variety of other great apps from BOLD, are awesome. They integrate well, they are maintained and their dev team is second to none. I've been using their stuff for over 4 years and almost 2M in sales!

Finally, a real email marketing tool. This is so well integrated with Shopify you can make such powerful decisions about what to send, to who and when - all based on a wealth of customer data sourced from Shopify. Once you start using Klaviyo, the data collection begins for real and you can marry user behavior in email with the shopify data. Hands down, the best email marketing tool in shopify.
