There is a good deal over at Tiny Prints if you need a self inking stamp. We just moved and so I have been waiting for a deal like this to get a new stamp.
I get a very plain basic stamp and use it when filling out all the kids paperwork!
There are a ton of designs to choose from and when you check out use coupon code 50DEAL1017 to get 50% off your order! Go HERE to get started
