<Where can I get discount t-mobile prepaid refill card? I'm mostly
interested in the $100 (1000 min) card. >

Enter cheap for further discount in the coupon code - you also accumulate
points for money of on future refills.  DonnaB  PS  Excellent site - just
used it today myself.

    As someone else mentioned, http://www.cheapphonecards.com and
they also used to have a discount code for another 5% off of "refill5".
I just tried that though and it doesn't seem to work any more.  Anyone
else know if there are other discount codes that still work?  Either
way, it's still 3% less than face value right now.

    If you do go there and sign up I wouldn't mind you putting my
e-mail as the person that gave you a referral.  They give referral
points and it doesn't raise the cost of what you're buying, just helps
the other person out, so, why not?!  :)

    One other thing you save some money on by buying online, and
this may be area specific, is sales tax.  It probably depends on the
store/state but some seem to add whatever the local sales tax is onto
the $100 cost of the card.

Office Max sometimes sells them 10% off.
