Taking Money

No owning a credit card, I'm often disappointed when web stores accept neither debit cards nor on-line payments (such as PayPal).
I think it's a bloody disgrace, especially as you only usually get to find this out when you've been through the tortures of registering on a site, and you're just about to pay.
Most recently, this experience was with Expedia.co.uk. They say the take Switch/Maestro, but not for all purchases. So, when it came to buying flights to Thailand (these cost > £1k for Amy + I), I was disappointed when I got through their procedures, entered passport numbers, set up meal preferences, only to find they didn't want my money.
Anyway, we ended up buying them from someone else.
The point being that if your site doesn't serve your (potential) customers, they will go somewhere else. I know I did.
