Ever consider laser hair removal? Granted the fee is all upfront but in the long run it's cheaper to do then buy wax strips every week. Many LHR offices offer specials/coupons/new patient discounts and are physician operated.
I have a girlfriend who went through it and she said it didn't hurt, that it felt like a little bursts oh heat. It's been about 20 years since she has had it done and still looks good. She says she has about 4 hairs that keep coming back on her arms but that doesn't bother her since she was dealing with "hairy dego" status before. She had her lip, chin and arms done.
