How about a sale for let's say 50% off?! I just marked down almost all the stamp sets in the section of the store "Rubber Stamps Holiday" 50% off. This is the only catagory/section that has been marked down, so you may see the stamp set in another section for the regular price... you will need to purchase it from the "Rubber Stamps Holiday" section to get the discount.
There are tons of Christmas and other holiday stamp sets availble that I am sure you will love. At this price why not pick up a couple extra sets for gift giving?
