Does anyone use Wowcher etc and have have you ever actually found a bargain?

Wowcher absolute RIP OFF I thought I’d bought deal so waited for it to come thought it was taking its time so looked back on my emails finding the deal needed ordering and I’d missed the deadline even though they’re still selling what I ordered I can’t get any money back that’s it !!! I don’t think they make that clear I’ve ordered multiple deals from Groupon and never had these problems.Not a normal process but you have to read the small print to find that out, it’s sharp practice just another scum company out there. Preying on naive people really sorry I trusted them 😒
