A scam used by a lot of local Chinese people?:

Groups of them seem to memorize the same phone number to enter for the local chain pharmacy's discount account, since when I'm in line behind them and so I can see the checkout screen, the name that pops up isn't associated with a picture, I can see, and it has a shit-ton number of points associated with it, way too many for just one person or even one nuclear family.

It makes sense - it's not like the clerks care, and either they don't know enough Chinese to know whether it's a male or female name, or they're Chinese heritage and they do know, but are they really going to bust someone?

I've heard that groups of local (Chinese) people have been making a killing on the real estate market, since they pool resources and wait till prices are low and then pay in cash...

This must be the same group approach, but with pharmacy discounts.
