Cncpts is 100% legit. I've ordered from them multiple times. It's a boutique store so they may take longer to process orders. Plus, they ship with UPS Ground so orders won't get processed on weekends. You should hear from them tomorrow or the upcoming days.
Kicks-crew is legit so you won't be getting fakes haha. I think they dropped the price since they received a huge re-stock a couple of weeks ago. I believe the prices were around $220-230 before the re-stock.
My credit card's billing address is different from my shipping address and I've never had any problems with ordering from Finishline, but that's because I added my card to Paypal and it makes my checkout/transaction process much easier.
