I have set up a form which sends user to paypal for payment. When I look at the form, it seems that users have tried purchasing several times - some with luck and other not so much.
That shouldn't be a big problem. I just figured it was something to do with response time and the like of the website.
I started comparing the form entries with payments in Paypal and things aren't looking good.

Annette Hilbert only paid once according to the Entries but twice in PayPal. The same goes for Amalia Garcia.
