When may a seller reclaim goods from a buyer?

Hypo 1: Sam sells scarves. Bob runs a small fashion store at the mall. Bob is a horrible business person. He's been getting closer and closer to going bankrupt each month, and yet he keeps trying to make it work. Bob believes Sam's scarves would bring in more customers, so he places an order for 1,000 scarves from Sam with payment due in 90 days. Sam is a careful seller so before he accepts the order, he visits Bob's store and see's how empty it is and how few customers there are. Sam calls Bob up and asks if he's sure 1,000 scarves are a good decision right now. Bob assures Sam that everything is fine and to please rush order the scarves. Sam sends the scarves. A couple weeks later, Sam checks up on Bob's store to see that how poorly it is doing and see's a "Going out of Business" sign hung in the window next to his scarves. Sam immediately sends a demand for the return of the scarves. Bob says, "Woah, woah, we agreed I have 90 days to pay you for them." Result: These facts make it clear that Bob was insolvent when he made the order, and that he misled Sam about his financial stability. As such, because the goods are still in Bob's store, Sam can reclaim them even though it took him longer than 10 days to demand them back.
