Step 1) http://pulse.ebay.com/ - learn to love this site. Even better learn to love http://pulse.ebay.com/index/20081_1 and find a sub category and see what is hot currently
step 2) www.o.co search for the product you have in mind selling that you found has a hot market
Ebay Product that is selling : http://www.ebay.com/itm/ZIPPERED-BLA...item1e6bbf9be6 $27.99
www.o.co link - http://www.overstock.com/Crafts-Sewi...7/product.html $22.49 (plus if you pay $20 a year you can become a o club member and you get back an extra 1.12 on that product plus FREE shipping)
step 3) ???
step 4) profit
How do you handle the shipping of the product?
You just buy the product after you get the payment to your paypal account from your ebay listing.
O.Co ships it for you. It comes pretty damn fast aswell :-)
Just tell your customer to send it back with the return label that o.co provided and once o.co gets it back they will refund your paypal account so you can refund your customer
Do you do this?
No but i have two family members that do this full time.
Will you show me their ebay store?
No because this is sorta a grey area :-) No one has said you CANT do this but no one has said you can do this ;P
Disclaimer: this is not my own oringal idea. its pretty old and common and alot of top ebay sellers do this
