The checkout now tells you what your card is actually charged

If you buy in Turkey, our catalogue is priced in dollars and your card is charged in lira. The checkout was built to tell you that before you paid — it worked out the exchange rate, took the Central Bank's published figure, and had the sentence ready. You never saw it. The rate reached the page and stopped one component short of the screen, so every Turkish buyer read $15 and met ₺741,60 on the payment form. Nothing failed, nothing was logged, and the amount charged was always correct — the only thing missing was being told.

That line is now where it was always meant to be, with the rate and the bulletin date beside it, so you can check the number rather than take it on faith.

The rest of the screen changed around it:

The total stays with you. The order summary sits alongside the form on a wide screen instead of scrolling away above it, so the figure is still there when you reach the last field. On a phone it comes first, before you type anything.
Three steps, named. Paying means leaving our site for your bank and coming back. The screen now says so up front, instead of letting the page swap itself for someone else's payment box unannounced.
What happens to your card, in writing. Your card details are typed on iyzico's own page and never reach us; every payment goes through 3D Secure; and the cancellation and refund terms are one click away. All three were already true. None of them was written anywhere you would read.
The discount box is out of the way. It asks every buyer a question almost none of them can answer, so it now waits behind a "I have a promo code" link. If a referral discount applies to you, it is applied automatically and shown on the summary as it always was — that has not moved.

After you pay, a completed purchase looks like one. All six outcomes used to render the same grey strip, so "Payment successful" and "We couldn't confirm your payment" were the same shape in the same place, and you had to read carefully to find out which had happened. A successful payment now gets a confirmation of its own, says the receipt is on its way, and links you to your invoices.

One more thing, for anyone who already has an account: Choose Pro used to send you to the sign-up form, and since you were already signed in, you were bounced to your dashboard instead. The button you pressed and the page you landed on had nothing to do with each other. It now takes you to your plan.
