I’ll add that I’ve found that the more you use Affirm at least, the better my options get.
I started by always choosing the shortest “plan”, which was 0% and no fees. After I’d paid off a few of those, I started getting offered plans of up to a year with no interest and very minimal fees.
Now, while I don’t use Affirm for luxury/unnecessary purchases, it offers better rates than any credit card I have, and better than a bank loan in many cases.
I have three Affirm loans right now, for a total of about $8k. All three of those are business expenses, and all three have increased profit in our business significantly more than they cost us.
