What is the secret to buying a INSTANT REGRET KIT? Every time it’s ever offered and I’m ready for it by the time I’ve proven I’m a real person it’s sold out. This has been a problem for as long as Meh has offered them. Always sold out in ten seconds. What can a poor boy do? At this point I expect it to be crap but I don’t care. I just want to know the secret. What do they sell just one at a time?
