So far, I haven't really found any particular retailer's sales all that amazing across the board. I always just sort of browse through whatever I come across, sign up (temporarily) for a few different retailer's email lists, etc. and wait for things to catch my eye, realizing that I may well miss one or another "bargain," but will hopefully make up for it by finding others... And if something does grab my attention but I'm not really familiar with regular pricing, I Google it to within an inch of it's life before actually buying, unless it seems truly dirt cheap and can easily be returned for a reasonable period of time (and usually that, only for brick & mortar purchases, since shipped returns are generally a PITA.)
