Are you processing over $3,000 per month with Paypal?  If so, you may not even be aware that you are eligible for a discount with the merchant rate!  Paypal does not tell you about it, you pretty much have to figure it out on your own!!  Okay, so here is how you get this discount:

Log into your paypal account.

copy and paste this URL:
https://www.paypal.com/row/cgi-bin/webscr?cmd=_fees-rate-about

you will find a page where you can fill out a quick form and if you have processed over $3,000 the previous month, you will get the discount rate automatically.  That's it....simple as that ;)

Instead of paying 2.9% you will have the following discounts:

$3,000 - $12,000 you get 2.5%

$12,000 - $125,000 you get 2.2%

so this little hidden trick can help save you hundreds to thousands per year in paypal fees!

Hope this helps ;)
