An employee of Best Buy apparently thinks too many days have gone without us posting something about the store, so he sent in his list of 10 things he thinks every customer should know when shopping there. Items 10 through 7 are all about warranties and service plans, so the usual caveats apply (make sure you know what’s really covered, and that it’s worth the extra cost to you). #4, however, is good to know: “Its pretty much pointless to call Corporate/Customer Service Hotline—they can not override a store’s decision. Best bet is to call or email a District Manager or higher.”
