She got suspicious when her online companion kept asking her to buy stuff and ship it. She didn't catch on immediately, and the family had to explain to her she was doing something illegal and that it was a scam (even though he was reimbursing her).
(She later did remarry a non-scammer, so happy ending I guess).
I think it was to get around embargoes? This was probably late 90s, early 2000s so she was buying stuff at like Circuit City/Walmart/etc and shipping it off.
