Email an offer to previous PayPal customers

I want to send a special offer to my previous PayPal customers but the problem is PayPal does not allow me to just identify my payments received but I have to download all payments (in various formats, comma delimited, tab delimited, etc). After I have downloaded the file, I open it in Excel and now I have the task of sorting thru all of the entries and deleting the ones I don't want. There has to be a better way. My customers who have purchased from me have only bought 2 different products so it would be easy to identify on a spreadsheet. Your task is to find a way to generate a list (with names and emails) of my PayPal customers who have purchased my 2 products.
