[quote name='RallyV']When you enter these contests, do you get texts from the companies after entering trying to sell stuff? I'm thinking about entering but don't want ads sent to my phone or put on some mailing list.[/QUOTE]
First, do yourself a favor and get your cell phone on the no call list.
Second, you can always text stop and they legally HAVE to stop texting you, that being said, I've won damn near $100 in microsoft points from 5thfinger promotions and never gotten text spam.
