You still have to have a credit card to get a paypal account and I've tried to talk my dad into letting me do that but it won't work. You wouldn't know it reading this, but I'm going to be 20 in a month and I'm not allowed to use my own money to buy things online.I'll finally be moving out soonish and I'll make sure I have enough money to buy a proper thermostat as soon as I get the chance. I don't mind checking temps more than one time a day and once I get it perfected, it should be okay until summer rolls along and the house heats up.
