How do I wait for an invoice?

[*sweettooth*]

I want to buy an item but sellers description says wait for an invoice. Ebay however has no option for me to wait. The only option is to check out and pay.

This happens when the seller does not require immediate payment for the item. From your question, it sounds like a listing error and it would be best to contact the seller first before making your purchase.

Contact your seller and ask them.  They know what is happening on their account.  Your seller should be your first point of contact with a question.
