You probably don't want to use bank transfers, depending on your jurisdiction. Using any sort of visa/masterdcard/amex gives you some protection via chargebacks. In the UK (and I think many other places), paying with a credit card over £100 gives you enormous additional protection (the credit card company is also liable for any problems). So if someone goes bankrupt, the credit card company has to make you whole. This is super helpful if eg you can't do a warranty claim on a product because the supplier went bankrupt. The credit card company has to resolve it (which generally means a full refund). Paying with bank transfers completely negates all this protection. Merchants love it for this reason (and lower fees), but as a consumer it offers no benefits and a lot of drawbacks.
