What it is

A specialty web store selling glass blocks in different sizes, patterns and finishes, plus spacers, mortar, sealant and reinforcement. Orders ship straight from a manufacturer or distributor, so you don't need a warehouse.

Your first three steps

  1. Contact several manufacturers and distributors to ask about reseller or drop-ship terms, minimums and freight costs
  2. Pick a niche, such as basement windows, shower walls or decorative partitions, and build a small store with clear sizing guides
  3. Get your resale certificate or sales tax permit if your state requires one, then test-order a sample to check packaging and shipping
Who pays

Homeowners doing bathroom, basement or shower projects, small contractors and remodelers, and installers who want an easy source of specialty patterns.

How it makes money

You earn the markup between wholesale and retail price on each order, plus margin on add-on items like installation kits. Helpful guides and size calculators can win you search traffic.
