My favorite sites still are www.budgetgolf.com, www.rockbottomgolf.com, and www.globalgolf.com. Be sure to sign up for email blasts so you can get in on the promos they don't always post on the site. And be sure to check out the clearance tabs if you are looking for a great deal!!
Also, if you are a Facebook person, be sure to check out store sites there, too - you can find special coupon codes, contests, sweepstakes and more!
I recently did some browsing on Ebay and found a great site for some really nice Cutter & Buck women's golf shirts - I've ordered a few just to see if they are as good as the deal says!
I'm trying to resist the temptation to buy any more golf shoes or clubs but when I see the word SALE, it's tough to resist!
