Certainly a great PR move, and great that these few people are getting good service. I would be concerned that customers aren't getting this service when sending their hardware back through the typical channels. I suppose it's just a side-effect of automating RMAs to provide faster service for their customers, where it results in RMAs being started faster (during off-hours, holidays, etc) - and therefore get resolved faster, but it seems customers don't always follow up and request a CSR to make sure the transaction is consistent with Newegg policies and procedures.
It seems like an awfully common complaint (based on this thread) that an auto-RMA service resulted in an unsatisfied customer. I wonder if it might be beneficial to redesign the contact/confirmation email that goes out as a result of the auto-RMAs to point out clearly the most common questions or issues that result from the automatic RMA process. If there already is an email going out, maybe it looks too automated and people ignore the good information in it. Perhaps it could benefit from a redesign that addresses the most common issues more clearly, and doesn't seem so packed full of legal jargon/releases/etc.
Just a thought. To be clear, I've done an RMA through Newegg only once, and it did seem to take an awfully long time (always does when you're wanting new hardware). Anyway, I did begin it with a call to a Newegg CSR, rather than using the automated process. I didn't have any complaints.
