Service sourcing cheap/non-working phones for trade-in programs

The user clearly says they don't need a working phone, just something for a trade-in. This points to a specific issue: getting a low-cost device just to meet the requirements of phone trade-in deals. A service could tackle this by sourcing, collecting, and reselling inexpensive, even non-functional, smartphones of specific brands or series (like Samsung S or Note models). The advantage for users would be maximizing savings on new phone purchases by taking advantage of trade-in offers without giving up a more valuable or functional device. This service would cater to a niche but clear demand for "trade-in fodder" phones.
