Advertising can get expensive, and since I don't have money to throw at the issue, I've had to get somewhat creative. I can't afford advertising on traditional media, and my shops are small ones anyway, and the items wouldn't appeal to everyone. What I do is focus on social media advertising, since I can do that myself. I built up a presence on Twitter long before I opened these shops, which gave me a platform for advertising my items. Hashtags are very important, because they enable tweets to be seen by a much larger following than I have. In addition, I have connected with other sellers through Twitter, Facebook, and my shop platforms, and cross-promote. By cross-promoting, the other sellers' items will be seen by my followers, and my items will be seen by theirs. The more people who see an item, the greater the chance that it will be sold, and in addition, there's a better likelihood that once someone has been to a shop and liked what s/he's seen, s/he will return for future purchases.
