I don't find it to be that hard to hit when spread throughout the year. With GCU, pretty much all my game purchases end up from Best Buy, and that includes gifts. Combine that with Black Friday sales, and diverting making purchases on Amazon to be at Best Buy since they price match, and it adds up pretty quick. Plus, if you make one major purchase for the year, it almost guarantees you make it. It's only $125 a month. Two games will easily hit that. You just need to realize it adds up over time.
Early access to sales like this and Black Friday, increased rewards points which means further discounts, free shipping with no minimum purchase, and increased return period policy isn't bad. Being done with and having everything already shipped and delivered to you before Black Friday without even fighting people online for it in itself is worth it.
