Do I need to pay £10 every time I enter the country?

Upon entering Turkey, UK citizens will need to pay £10 per person for a visa. Even though this visa is valid for 3 months (90 days), it will be a single entry visa, which means that the client will have to pay £10 each time they enter Turkey. However, if they ask for a multiple entry visa (same price of £10), then when they next return to Turkey, if it is within the 90 day period, they will not have to pay the visa fee again.
