I'm on a pay-as-you-go mobile phone plan, with no free phones for sticking with a monthly service plan.  When the battery on my old phone started dying, and I was going out of town for a week, I went to a couple different stores to find the phone I was looking for, an inexpensive ($15) model.  Everywhere was sold out, and they all tried to upsell me.  They didn't have the $15 phone... but would I like the $60 model?  

 Frustrated, I was walking home when I saw the best buy mobile store.  They actually were carrying the phone I wanted.  Someone offered to help me out immediately, and when I said "I just want this phone", he didn't try to upsell me or anything, and offered to take my old phone and charger as part of a plan they have which would discount the new phone by $15, making it, in effect, free.  

 I was extremely happy with the service I received at this store.
