I agree that JRR could run a much tighter ship and invest on a robust e-commerce solution, particularly since this is not the first time their site disappears.
On the other hand, what is the risk for us, the users? That they steal our JRR credentials?
I'm asking an honest question.
The other risk, which seems less likely, is that the site is hijacked and PayPal payments are redirected to a third party. I don't know how likely that scenario is and whether PayPal would reimburse us in that scenario. If that's a concern, one could PM Uncle E directly to request a PayPal invoice. One double checks that it's coming from JRR and if the transaction is not honored, I'm pretty sure PayPal would reimburse us in that case.
I'm not trying to shill for JRR and it's a personal decision to transact with them or not, but I think the e-commerce world has evolved through trial and error so that the risk for the consumer is lowered. The end goal of our capitalist overlords is to keep the engine greased and going and ***** they've been doing their part.
EDIT: LOL, a very mild word was censured. You know what? **** that *** you **** ****. LOL!!!
