It is a different kind of product and while you used to be able to get it through home depot, you have to order it from the supplier in MA now, I believe.

Suppliers-talk to his chemical supplier and maintenance guy.

@Liam Hanlon whether your looking to replace your cabinets for this project or in the future I would recommend finding local cabinet suppliers and setting up an account with them.

The cost of materials and labor is exploding I don't care what the headlines show - every supplier and trade are increasing what they charge quarterly.

Personally I do not mind bringing business somewhere else, last year I bought 3,000 angle stops and 3,000 faucet SS hoses, sent them a sample/spec, HD sells them for $6-8/pc, supplier prices were $1-1.15/pc, spent another $.50-.60/pc on air cargo and etc.

I'd prefer a wholesaler, small company, or reputable online supplier...

Kent here is the difference in your analogy: I don't have access to Walmart's suppliers.

I should clarify-I work for a home materials supplier (flooring, toilets, tubs, tiles, the whole thing) and am able to get most of the materials at wholesale price, so that's able to cut down on cost by quite a bit. 

Additionally these high-end modular's price point is higher than comparable site built projects unless it's in a remote area where labor and suppliers are scarce.S2A could be successful, in my opinion, if they had a quality product sold and installed through capable, competent, contractor/ dealers.

The supplier pays me a commission % for the dollar amount of goods I sell to restaurants.
