You might get an envelope from Netflix which has your address preprinted on it, instead of on a stuck-on label. You open it up and discover that inside, the return address says "nearest Netflix shipping facility". Instead of your local distribution center, it has an address for a faraway center. Do not be concerned. This change was made to increase efficiency of distribution, and will not affect your service, according to Steve Swasey, Director, Corporate Communications for Netflix Inc. He says members should not alter their envelopes in any way.
I haven't noticed a problem with it, myself, but if you think this is affecting your service, complain to Netflix.
