Well that was a quick decision!
My usual gameplan when that happens (or with big sales in general, really) is to get little things that I've been wanting. Because once you're an advanced reviewer (if you're not, submit a class request in the mentor program! You get a little friendly insight, and you can graduate after doing 2 reviews with your chosen mentor.) You can have 30% off an item at any time, in exchange for revirewing it within 3 weeks. So I like the sales for getting lots of low-cost items, like books and nipple clamps, that I've been wanting, but don't want to be on a time-crunch to review them. Then do a buy-out on your big item later when it's in stock.
(PS---the WV3 is awesome.)
