FYI - For me personally I've avoided buying anything from Canada on Ebay the last several years unless the item was something I really wanted and wasn't available elsewhere. The shipping coming from Canada to the US was always slow, the tracking was worthless, and it also seemed really overpriced in most cases given that we're just across a river from each other. Maybe my bad experiences were just flukes, but it left a bad taste anyway. You don't want irate buyers trashing your feedback though, so do warn about potential delays on international orders and whatever else you feel is relevant such as where you'll ship to or not.
As a comparison... I was recently looking for one of the cheap old-style DIP IC puller tools. I refer to the kind that were just a plain U-shaped bent piece of flat steel with the tips bent inward toward each other, meant to grab like tweezers under the ends of a chip and pull it out of a socket. I was sure Radio Shack would still have them, but no they didn't. I then went to the few remaining electronics stores around Detroit that Rat Shack hasn't put out of business yet, and nobody had them! Apparently since DIP package IC's and sockets are much less common, the puller tools are also rare as hen's teeth now? And it really bugged me since I know I have a couple of them lost around the house somewhere, maybe still in a box from a previous move. Anyway I did see a bunch of them on Ebay though, so I bought one from California for around $3.25 just to get one quickly. It was also nicer than the old ones, with a dipped plastic grip on it. I also couldn't pass up what was an identical item (except for color) from China for only $1.16 apiece including the shipping! I ordered 5 just so this would never be a problem again for me, and guessed it would probably take 6 weeks to get them all the way from China? I was truly amazed when they showed up only a day or two after the one from California!
