Sign up for lamkin emails, they have specials from time to time and free shipping Fridays every now and again....the standard size wrap tech grips are half off right now.
As for other deals, take a peak at DTG, typically they have the best prices and also some kick-ass sales which include the 13 grip packs with tape and solvent.
Hireko...the Karma velvets are pretty good....I think they renamed them to velour or some BS name like that.
