Why? I'm a deal junkie. I love to save money and try to buy in bulk to do so. Therefore I end up with a stockpile. Most of the balls I buy are much less than retail. Yes they will all get used.
Yes, for exactly the same reason. If it is a deal, I am tempted to buy it!!
I bought 1,000 tees off ebay cause they were a good deal. Also buy used golf balls when there are deals to be had. I have about 150 used balls right now that I bought in two different lots.
Those deal sites and daily emails are my nemesis.
