Earlier this year I got some quotes on some metal storage sheds. Most of the quotes were in the $2500-$3000 range. Last week I got some more quotes, only now, those same buildings are all over $4000. The places that are giving me the quotes are saying the price of steel has gone up 15-20%, but that doesn't account for all of the price increases. Does anyone know why the prices of these buildings has gone up so much?
