How do I purchase two items and not pay for them right away so that I can recieve an invoice?

[ca_nave]

I want to purchase two items from the same seller but not pay for them so that I can invoice for them and then pay via paypal.

Please help!!!

It is all depends on terms of sale. If seller stated - Immediate payment required, you can only buy one by one, without combined invoice.

Before bidding, contact the seller and explain what you want to do.

He may refuse and he is allowed to do so.

Or more likely he will be happy to oblige and may offer discounted and combined shipping.
