#1 rule of sales. If someone is trying to sell you something, you _probably_ don't want it. Eg, they need the sale more than you do.
The very fact that they were asking the question is such a huge red flag.
I've started telling basically that to the solar salesmen who come by every few days: if it was so great, you wouldn't have to pretend to be from PG&E or tell a bunch of half-truths about how utilities work.
Them needing it more than you doesn't mean you don't need it too.
Bought an air mattress recently. Way better than a sleeping bag on the ground, even though I can also manage that.
