Batch pricing

Batch pricing relies on blended valuation: mixed-grade lots are priced from weighted averages of constituent grades, then discounted to account for uncertainty and sorting cost. The lot discount against unit-level pricing often represents a liquidity premium paid by sellers for speed and transfer of grading risk. To evaluate fairness of a batch offer, sellers need up-to-date condition-level unit pricing as a comparison baseline.

The size of the batch discount varies with the predictability of the lot composition. A lot sourced from a single corporate fleet with documented grade distribution commands a smaller discount than a mixed consumer trade-in lot with unknown cosmetic spread. Buyers price the uncertainty in lot composition into their offer, so sellers who can provide accurate grade distribution data before negotiation typically achieve better per-unit prices than those who cannot.

Batch pricing also creates an information asymmetry problem. The buyer, who will sort and grade the lot, has more post-purchase information about its actual composition than the seller had at the time of sale. If the lot turns out to contain a higher proportion of Grade A devices than expected, the buyer captures upside that was not reflected in the negotiated price. Sellers who invest in pre-sort grading or statistical sampling of large lots before offering them for batch sale can recapture some of this upside by improving the accuracy of the composition data they provide.
