ISO supplies in Boise/Meridian, Idaho area

Just wondering if anyone in the Boise/Meridian, Idaho area has yarn, circular needles or other supplies they’re willing to get rid of at a low price? I’m just starting out and don’t want to spend a lot of money (in case I just can’t get into it) so I’m looking for stuff you need to get off your hands for a cheap price.

Thanks, in advance!
