I have refrained from sharing as I'm not committing yet. I am, however, commiserating with you guys about how it's a good idea to sometimes take a break from that activity. I'm just not sure if it's an idea I "need" to partake in. I literally just bought myself some fun accessories after the break-up 3 weeks ago. And you want me to give them up!?! :)
I generally buy mine online through Amazon, and Amazon appears to have a universal return policy. I just checked and I could return it (if I wanted). I would hope that they would not resell it. However I have heard a horror story about someone ordering an accessory online, getting it, and being able to tell that it was used. As for a warranty, I can't recall and I think I've disposed of the box and any warranty that would have come with it. It probably depends on the item. The Hitachi Magic Wand which is pretty high end, expensive, nice, etc comes with a 1 year warranty. It probably depends on the maker and vendor and such.
