So many people on this team have given wonderful advice on many different threads I"ve read, I'd like to pay a little of that forward if that's ok.
Not too long ago, I was waiting (and waiting) for my first sale and getting quite discouraged and I took lots of your wonderful advice......one thing that has REALLY helped me get some sales is relisting an item or two each day consistently. I"ve done BNRs (and I Love them.....its quite addicting, its alot of fun, you meet new people and it does help) and I've done some showcases (which I do not think helped at all) but most of my sales (17 to be exact now) have come from a relisting and getting my product up at the top of the list, or someone noticed one of my relistings and was kind enough to use it in a treasury and it was noticed there.
Even to list or relist one item a day, is not too much out of pocket in the grand scheme of things, and I think it really is the biggest way I've gotten sales.
I hope this helps someone as the advice here has helped me.
