Unfortunately they posted their terms, when I clicked it, they said the terms for cancellation are within an hour of purchase. And something about after its shipped you have to pay the freight costs from and then back to along with a restocking fee. That gives them leeway in the disputes.
If I go to Best Buy for example I couldn't find any terms of sales on their website under its own section. Also the sales people there are paid minimum wage and don't know much about what they sell. Same when I go to Lowes Garden center, I asked a few basic plants questions and the lady in the center looked at me and said she doesn't know anything they just tell her to put stuff out.
