How Can I Get My Pepper Seeds to Germinate?

I'm trying my hand at gardening for the first time this year and I've got some pepper seeds that I sowed about 13 days ago. The seed package claims they should germinate in 10-14 days, but nothing has happened yet. I suspect the cold temperatures in my basement might be the issue, as it only gets about 5-10 degrees warmer than outside. Should I move the seeds to a warmer room and give it another shot, or should I just start fresh with new seeds? Alternatively, is it worth considering buying some pepper plants from a store since we're already halfway through February?
