We recommend avactis to all of our customers as it is very flexibile and can fit any design you have. It is only $200 (one time), you can find a reseller who will do customizations for the same price. Or you can look at open source carts like osCommerce, zen cart, etc.,
maybe the best to do is open an Ebay store, instead of having ur very own store. Electronics and electrical parts shipped over China or India is the best to sell, due of their cheap prices. Good luck
I can do better than an ebay store and I don't want to sell electrical parts. Anyway it seems that good ideas dont come easy.. if i'm going to figure it out I will post it here.
You may have had a proper idea anyway where you mentioned gadget-like stuff to sell. You can create an online store of a different kind where you only sell 1 item a day which you have bought in bulk/made sure your dropshipper has enough in stock. There are a few sites like this which have taken off - 1 deal a day is shown with a funny/good blurb which may include a video and have a message board functionality setup as well - you also give an email opt-in for the deal of the day gadget to previous customers and with the forum users should have a customer base that grows daily. PM me for a couple of example sites which I use myself who employ the above methods if it interests you.
