I ordered a new kitchen sink off Amazon late last night, and VM Innovations had the best price so I ordered from them. As I got into bed I had second thoughts - what if the sink arrives damaged? I should probably spend the extra $17 in tax and order it from Amazon, as I know they're easy to deal with and VM has a lot of poor reviews. So I cancelled the order and did that.
This morning I went to the sink's product page on Amazon and saw that the Amazon price had dropped by $25! Chatted with a support agent, got the second order cancelled, and ordered it again at the lower price. Hooray for second thoughts!
