A lot of sites add things like that because on average it actually does increase orders and has no real downsides. Not at much with the newer generations but if your target market is boomers then it can help.
Get Koho. E-transfer money into Koho, and use Koho to make purchases on weird websites.
It gives you a real credit card, but you basically treat it like a pre-paid card.
I love it. Takes less than 5 seconds for the money to get e-transfered into the account, and sketchy websites cannot make unauthorized charges if your account has no money lol
It's very much legit. A lot of animal medicine in America is restricted to just vets. Even flea medicine! I work in agriculture and always reccomed people to buy from there. It's cheap and available. The American health system is a joke. Even for animals
I've ordered real pet medications from there because american vet wait was two months in my area. It took a few weeks for the cat meds to arrive, but they definitely delivered. Cheaper than a vet in my area too.
