Anyone here heard of Southwestern Advantage?

[JammyGem]

Had a very nice young lady just knock at my door to tell me about Southwestern Advantage - seems it's educational books or something. I was in the middle of changing DD so tried to get away but she's arranged to come back later this evening.

Firstly, what can I expect? Are the books any good and is it a reputable company?

Secondly, someone help me become more assertive at telling people I'm not interested, especially when they get pushy!

Wait til age arrives and tell her you’re actually an evangelical (insert faith here) and would she like to talk about (insert deity here) while she’s over?

Apart from that: just tell her you made a mistake and you can’t take on any other work for tax purposes., sorry for her trouble.

I think she's only trying to sell them, but having a quick Google it looks like the company has been banned from some campuses in the US (no clear reason why) and it's not obvious whether they're individual books or some sort of subscription service.
