GAY ITT we guess what fly is selling on a'zon

fasttech.com is like a smaller dealextreme.

I usually get my flashlight parts from FT. Just made an order there a couple days ago.
 
In my experience, aliexpress makes cheap crap. Also, they don't sell the product I'm selling. I did use them once to source a component in my product and I was terribly disappointed. I should make a better Amazon page. It is on my list of things to do.
By optimize, I meant to fix your product page and do FBA. You're likely to get more than enough sales to offset the cost of FBA, unless your item costs less than about $15. Also, do you have a Pro account?
