One thing I like is deals. Whether they are discounts, sales, freebies etc. And it is always nice to get some kind of discount when buying domains. Especially if you buy in bulk domains.

Two great websites that help pass along the discounts are DN Coupons and Domain Name Coupons. Both sites list any current and or up to date coupon codes for major domain registrars, such as Godaddy, Namecheap, Dotster and a handful of others as well. I have found these coupons useful and handy when trying to stretch a few dollars.
