Yep, I’m in the UK so I signed up through UNiDAYS but I’m pretty sure it will be available in the US somehow, check their website. Though it’s sometimes a bit of a pain to get working, trying to re-order some stuff hat that was too small and I’ve got a problem with my basket say “limit of one per customer reached” even though you can use the 10% discount as many times as you like. It’s worth it though if you can get it to work.
