You do not need a study says retailers that 95% of the profits that are registered as disabled is absolutely not. The return of goods over time for various reasons (do not pass the test's wife, son of ungrateful inappropriate, would rather spend $ 150 on jeans later new phones, et al).
If your gadget is broken or user error or problem You would rather spend your money on something else is irrelevent. The problem is the restocking fee. If You have all the original packaging of your items and returned in resellable condition within an appropriate time frame, and with Your receipt, You must not charge restocking fees are applicable. However, many electronics store will cost 15-30% restocking fee except for damaged items.
Consumers cannot be ' smart ' enough or they might be ' too lazy ' to learn new technologies, but they are certainly smart enough to understand that if they tell the officer disabled items they will get a full refund and be long gone before the shop had a great time to test items and realize it works, especially if they return items after Christmas. Poor workers make $ 8/hour only processed 50 back in 4 hours, do you think they care if consumers are telling the truth or not? No, injured their legs and they are counting the minutes until lunch.
It also depends on the definition of disability. I hae just return one thing –-AM/FM clock radio that only hummed on AM. Since that is the reason I got it, I'm back. I don't care if you meet some Chinese industry standards, or if the FM works.
