Hi, I'm reporting what seems to be a bug because I got caught out. I selected the €9.99 option, except that in the meantime, and it's hard to see, at my place, the button changes to €29.99...so thinking I'm paying €9.99, I see a bill for €29.99...I'll let this one go, but it's good to correct the malfunction.

Yes, it did that to me. So I didn't buy it.

default amount
so better change your amount after you select payment type.

Yes there is deception, it is very limited.

Same for me… I almost got had…

Indeed, if we clicked on a certain offer, then another one within a certain time, it is the price of the first one that could remain. This should no longer happen now.
