can i pay through bank transfer?

Welcome to the Support Communities. The Apple Store (UK) allows Wire Transfer — see under that heading here:

The Apple Store (US) says:

"Bill Me Later©, business lease, wire transfers, cashier's checks, and money orders are ineligible payment methods for pickup items. (...) Some customers may qualify for other forms of payment. Please call an Apple Store Specialist at 1-800-MY-APPLE for more information."

If you are referrring to the purchase of an iPhone or some other Apple hardware, contact the store from which you intend to purchase. If you're referring to the iTunes Store (where you buy apps for your iPhone, music, etc), no, you cannot.

Regards.
