Our apologies to those who were inconvenienced by the failure of our shopping cart this month. This was caused by changes to both USPS and our credit card processor's API scripts without notification. In theory these are now fixed. Please contact us if you have a problem.

The cart is currently disabled for all non-US orders, but we do ship worldwide. If you would like to place an international order please send us the list of what you'd like (sizes too) and your address and we will invoice you via PayPal for your order.

There are a large number of new designs added (and not all are on the featured page at the front). Note that we do not keep all items in stock in the warehouse (and it will state this in the item's description). On these items please allow us the extra time to get your item in for you. As we hit peak convention season please be aware that we will ship orders as fast as we can when we are in the office but we will be out of the office a large number of weekends. As usual for any questions please email to pegasushelp@gmail.com.

Game of Thrones is this year's hottest show and we've got the shirts to go with it.

We are continuing a major upgrade to the shopping cart mechanism on the site. Unfortunately until this is done the cart does not work with Google Chrome. Please use Firefox or Internet Explorer for best functionality. Also foreign ordering is temporarily not working but we'll be glad to take your order. Please email us for instructions

As usual if you have any questions feel free to email pegasushelp@gmail.com or call us 903 989 5351.
