Chris. I just got 2 sleeves of balls from Golf DataTech for filling out their surveys the past 3 years. The cost was $4.95 with the Post Office. I know they used to have a 2 pounds or less package rate for $3.00 if I remember right. But that was a few years back and I don't know if they still have that or not, or what todays rate would be.

Wonder how much a sleeve of golf balls weighs... I think you can still use a first class stamp up to one ounce, right? Might be able to get away with two or three stamps... still, less than $5 is not a problem...

Chris you're probably right, but I think it'll depend on where it's going. But I'd stop in to the post office one day and just ask them...

Each ball weighs 1.68 oz. plus the wt. of the sleeve.

A fountain of knowledge, thanks Bill. OK, so I need to get these ordered. I think I'll pick up some padded mailers at Costco or Sam's Club. I'm sure they have them there. Thanks everyone for your input - stay tuned.

Chris, it's not just the weight...if the envelope is not the standard #10 size they charge more also. Once you get into the padded mailer, you need more than one stamp, plus they may have an issue with the "girth" (mark it "hand stamp only"). Have one checked out at the post office.
