DD101, EGC = Electronic Gift Card. When you spend certain amount, you get a certain amount in gift cards for future use. I believe for $1000 and up you get $150 in EGC. $2000 and up you get $300, and $3000 in up you get $450. Max you can get in the store is $450.
Saks just had an EGC in Aug. Won't have one in Sept. Maybe Oct?
