Query: Disappointed by the price increase

I ordered two bumpers for $18.35 to check out the quality before I ordered more. I liked them, went back two weeks later to order more and the price had jumped to over $30 for the exact same bumpers. At that price you can buy something better at a marine supply store. At the old price they were a good value for the money, not so much now.
