Authorized wholesale retail, done right.

Crestline LLC purchases products at wholesale prices from brands and authorized distributors, then sells them through Amazon's FBA (Fulfillment by Amazon) program. Our customers receive fast, Prime-eligible delivery backed by Amazon's national fulfillment infrastructure.

We're not arbitrage flippers or unauthorized resellers. We build proper wholesale accounts, maintain brand integrity on every listing, and place consistent monthly purchase orders. Our goal is to be the retail partner brands want on their Amazon listings.

Based in Kansas with commercial prep and logistics operations in the Midwest, we receive palletized freight, inspect every unit, and ship through Amazon's fulfillment network — covering all 50 states with 1–2 day Prime delivery.

Authorized Supply Chains Only

We purchase exclusively through legitimate wholesale channels. No gray market, no liquidation, no unauthorized supply.

Consistent Reorder Volume

We place regular monthly purchase orders and scale volume as products perform. Reliable demand your planning team can count on.

MAP Price Protection

We use automated repricing with strict price floors. Your minimum advertised pricing is never violated — protecting your entire retail channel.

Listing Quality Standards

We monitor our listings for accuracy, report hijackers, and ensure your product is presented with correct images, titles, and descriptions.

Category specialization, not scattered selling.

We focus on categories we understand deeply — allowing us to track market dynamics, seasonal trends, and competitive positioning for every product we carry.

Cleaning supplies, vitamins, personal care basics, wellness products, and household essentials.

Cookware, kitchen gadgets, home organization, cleaning tools, and everyday household essentials.
