20 eur is quite uncommon, it's usually 1 or 2 usd/eur. So I skipped reading these two lines of unassuming gray text and entered details of my disposable visa with like 5 usd on it.

I think you are quite unique in 'skipping text' written nearby text boxes where you are entering your credit-card number, expiry date and CVV2.

I would recommend changing that behaviour ASAP ;)
