When you work for retailers you rarely get any type of chargeback...I haven't ever received a chargeback other than being charged back from DTV when I was a retailer. As far as installing goes I haven't received any of those charge backs you all talk about. I know they exist, my brother in law is a tech manager for an HSP, so I have heard, but I wouldn't like that myself. But there are people who install DTV that don't get any types of chargebacks...
