Oh, there's also Satsback.com. It supports a surprising amount of online stores and while sometimes it takes a while for my purchases to be credited, it's always worked! Just make sure to either do it in a VM or in the very least, in an incognito browser window since it's important that you accept all cookies. A great way to stack sats when buying things you'd (hopefully) buy anyway.
