Just wondering if any of you guys/girls have any experience buying balls in bulk (250-350 range). It's something I've been thinking of doing for a while but haven't gotten around to it yet. I figure a one time deal for new balls and a tumbler will save me years of hassle always getting new balls and hopefully save some cash. Shipping from the states seems to be insanely high due to the weight. Any place around here with a reasonable bulk discount or any place that doesn't eat up any savings in shipping costs?
