Hey, I purchased 2 mousepads and it cost me just under $6 with free shipping included. It's likely that you may need a paypal account to make the purchase. Here is the promotional deal going on when using the GW2MOUSEPADS code during checkout:
Mega Sale: $0.99 for first item, additional $4.99/each with free shipping.
Choose from selected Mouse Pads, Cosmetic Bags, Playing Cards, 3D Cards, Key Chains, Ornaments and Dog Tags.
And here's another Scarlet image cropped down to size: http://i.imgur.com/yKjeZro.jpg
If anyone needs help cropping an image to the right size, feel free to let me know or to have Reap get in contact with me. I chose one GW2 image and then an image from my favorite anime for my mousepads so it can really be anything but the larger the image, the better.
