You can also go to shoptext.com and signup for an account. Then when you text them, its only one message. Cheaper way to go if you don't have unlimited texting.
I cursed myself by saying I always get my samples from them. I just got a text message saying they are out of the samples of gum I ordered last week. GRRR!!!! I really appreciate their costing me money to send me a text message to tell me that!
