I think you should aim for X number of sales and 5 star feedback first. After you've reached that, then you can raise your prices if you want. Basically the aim of most new shops here is to look legit first, coz as a customer if i'm looking at 2 shops selling the same thing at the same price, comparing #of sales and quality of feedback tend to be the tie breakers. So just decide what that X number is for you. Hope this helps!
