Nomadic Supply Company Freight Versus the Big Box Stores

Nomadic Supply Company wants you to receive your valuable products in absolutely pristine condition so we ship our large refrigerators via truck freight, and we handle and package them in a way that no other retailer does.

When we prepare refrigerators for shipment we spend a full hour to inspect, re-pack, prepare, and schedule your truck freight shipment for the following day. This process ensures that your order arrives to you completely undamaged and in brand new condition. Our competitors do not do any of this for you, and they are are infamous for having their refrigerator shipments arrive damaged.

Our detailed inspection and repacking process will cause a minor delay in shipping your order to you, but unlike all of the other online stores, our shipments actually arrive to you in one piece, without damage, every single time.

  • → We inspect, repack, & double or triple box refrigerators in our custom made, dual wall, fully overlapped, 450lb. test-rated boxes.
  • → Nomadic Supply Company adds 2” Styrofoam and reinforcements to the packaging and all of the large refrigerators are fully palletized.
  • → We take photos of your shipment before, during and after your order is completed. Our customers LOVE this!

We do not recommend residential deliveries via truck freight:

Residential deliveries are always more expensive than shipping to the closest freight terminal. Shipping to the closest truck freight terminal in your area has numerous advantages over shipping to your residence:

  • → It saves you a ton of money in truck freight fees, usually around 50%.
  • → You can schedule to pick the shipment up at your convenience rather than spending a full day at home waiting for it.
  • → You can thoroughly inspect your shipment for potential damage caused by the freight carrier before accepting & signing for it.

You must read and understand the entire LTL Freight process if you want to order a refrigerator from Nomadic Supply Company.
