A review for Square stickers by cari.
After several attempts from my marketer/staples/ other printing companies- they could all do 6x6 stickers...one place actually wanted over 1k [granted minimum of 500]
I placed the order on a thurs and received on mon with a tiny fee 
Pricing was wonderful/ service-proof was quick and efficient and it was the first company in a very long time that exceeded expectations!
The final product is also wonderful- Thank you Sticker Mule- you have a customer for life!
