I want to start by saying that I have shopped at least twice from Discgolfcenter.com, primediscs.com, and know of people that buy from marshallstreetdiscgolfstore.com and sunkingdiscs.com among others. I've shopped once while my buddies have shopped a handful of times while even having one of my disc guys shop at the store on vacation. We've all received our discs within a matter of days with same day shipping. I know discgolfcenter.com has the best prices but they take forever to get to them to you. I don't think that's worth a savings of about a quarter or two per disc.
I do believe the reward system makes buying here worth the experience. Especially when they have deals like triple bonus points for reviews and purchases. I've run into a couple of people that have called the store to place an order and they shipped it out that day and were very easy to work with. I've always gotten the disc in the color I wanted and the weight with an added prize (bonus disc) just for purchasing a certain amount. I really like my experience here the best and will say that I will do much of disc shopping through Clearwater.
