I would like to sell purses, shoes, clothes, electronics etc at flea markets?

I have tryed the internet and found companies like doba, wholesale fashionsquare, etc. are not true wholesale prices.

So where can find wholesale supplers? (purses, shoes, clothes, electronics, etc.)

Do I need a reseller permit to sale at a flea market?

How do I qualify to attend tradeshows and are they expensive?

Note: I am in the state of Alabama and also interested in dropshipping.

I will choose a best answer. Thank in advance.
