unfortunately, they aren't that common. most of the time customers just go to another vendor because of trust issues, unless you cut your prices which I suppose makes it viable for them to take the risk.
no gateway to PayPal, no proper payment provider that works properly with foreign credit cards (apparently Turkey is in some kind of a banking blacklist so whenever let's say an American or a European uses a Turkish online POS (Point Of Sales Terminal) system automatically flags it as a fraud.
Stripe is also not available in Turkey. Payoneer, Skrill, and Transferwise are all available but it is really hard to find clients that use those.
Stripe is also not available in Turkey. When you open the Paypal website you see an announcement that says PayPal ceased operations in Turkey in 2016.
(Turkish government demands that any financial service provider should have local servers in Turkey but PayPal rejected it obviously because they only have 3 servers worldwide (USA, Luxembourg, Singapore) so their license to provide financial services in Turkey got canceled)
I don't think I would be able to use a foreign PayPal account from Turkey for a long time. Also how easy is it to open an LTD in the UK? how much does it cost?
