This was a similar post i made some time ago:
I am not being able to sell even one of my cards now for some reason. I know from a long time back that you are allowed to AT LEAST sell one card per day but now it's been like two weeks since i've sold any card and this message keeps on appearing:
To prevent cheating, the public and private sales (excluding sales to Kate) functions will be unlocked indefinitely after your first purchase of credits at the Shop (more information can be found in the Game Help section).
Can somebody please help me to sell my cards once again.
The answers i got for it were to buy credits, and then do a free offer that gives credits as a reward.
Can somebody please explain this answer as i do not understand this.
Also, my country (Fiji) is not on the country list in UR so i don't know if i can buy the credits.
You can either buy credits, *or* do a free offer that gives credits as a reward, which is found under the "free credits" tab, which appears bolded in orange after you select your country.
The country you select in the shop will only determine the types of payment methods, or types of free credits available. Some payment methods, like credit card via paypal, are pretty much universal all over the world, so you can select any country at random and just choose that
