That's better directed to Lolli. It's likely they do not accept prepaid Visa cards for their service, as there is no bank account linked to it.

We have Card Linked Offer too - ours function much the same (ie, prepaid cards won't work; it must be a card linked to your bank account).

I used to just activate the lolli extension at qualifying store and checkout using the prepaid card and I used to get sats back at Lolli. It used to work haven't used lolli recently not sure if they changed anything.
