You should be able to submit it without entering that information? Try that and see if you can still order. Also, I ended up ordering from this site: safegenericpharmacy.com which accepted payment from Paypal (although not via standard way — follow instructions). The other method was requiring payment through Bitcoin. Although it looks like my goods are in transit, I have not yet received them, so cannot attest yet to reliability.

Such a shame that we have to go through so many hoops to save lives.
