The RMA channel generally works one of two ways:
- Most common: Stock gets returned as it fails and credited at the original purchase price
- Quite uncommon: Buffer stock gets included in the original purchase price - eg, for every 100 purchased, you pay for 95 and the 5 "free" units are to be used for warranty replacements
#2 is and generally reserved for small orders where there just won't be enough faulty units to warrant return shipping, such as a distributor placing an MOQ order for a new brand of keyboard where there might not be a second order, or a retailer beginning to introduce a new product via direct import.
Warranty outcomes are not "the customer gets whatever today's equivalent product costs." They are "the customer gets the value of the failed product back through the warranty chain." Takealot credits the customer the price at the time of purchase, Pinnacle credits Takealot the price at the time of purchase, WD credits Pinnacle at the price at the time of purchase. That's the beginning and end of the warranty transaction between each pair of parties. Nobody in that chain is handing anyone a magic R 3k because the price of NAND happened to explode in the interim.
A warranty is not price insurance. You're not asking for a warranty, you're asking for a guarantee of price protection for the lifetime of the warranty.
