One shipping container quote may be much cheaper because it covers a lower condition grade, a different unit size or height, a closer depot, simpler delivery, fewer repairs or modifications, less warranty, or more cost and access risk left to the buyer. It can also be an incomplete or fraudulent offer. Ask the seller to explain the variance line by line instead of assuming either bargain or overcharge. Confirm every claimed saving in the revised written total before accepting the lower offer.

Ask the sellers to explain the price bridge
Send the same condition, modification and delivery specification to both companies, then require written clarification of every remaining variance. Reconfirm the final unit, route, unloading method and delivery date before accepting the cheaper total.
