Hi, i would like to know if the following method would work for not getting scammed with paypal:

- First use an escrow.
- Wait for the buyer to fund your paypal acount. and dont release till:
- you buy a cheap item in a site like DX.com and ship the item to the buyer.
they often take a snapshoot of the package and gives you a tracking code for something like $1,9. So you could use this as proof you shipped the item. And dont talk to paypal about you are selling bitcoins.
- wait for the tracking code, and the image (2 or 3 days) and
- realese the escrow.  


the posibilities of a scammer iniciating a dispute, are fewer when you have a shipped item?

using other methods is not usefull for me.
I need to buy bitcoins via paypal, becouse in my country are lots of restrictions to buy dollars (or other currencies) so when you travel is a huge pain in the pocket. Using credit cards and paypal, is easier to get dollars, at a cheap price. (there are black markets of dollars that cost much more)

thanks in advance for the help
