This will sound stupid to some of you guys that have done this a 1000x
If I'm buying product from someone on here for my M3 an they send me a invoice via PayPal an I pay the $ wit my credit card how do I know this other person will send product???? Should the PayPal invoice describe what I'm getting an when an how being shipped. Sorry but it's over a $1000.00 an I don't wanna get ripped. I know wen I order parts from the States for my Harley it's from a BUISNESS an invoice describes everything an it's not from someone personal. Thanks for the help Bimmer Bros.
