I'm going to be thinning out some traps within the next few months. I haven't shipped any in a few years. I was curious if it is still best to work with flat rate priority boxes?

I have had good luck with buying shipping labels on Pirate ship for tractor parts I have sold. It is pretty easy to use too once you set your account up.

I second Pirate Ship for the best rates.

Just make sure you do not overload the cardboard box. All cardboard is not created equal. Almost every issue I have seen with shipping traps was caused by too much weight in a weak cardboard box.

My nice ships a lot through Pirate Ship for a few years now and has had excellent results.

We have been using Pirate ship also. It has been cheaper.

Yep, pirate ship and line the inside of your shipping boxes with duct tape as it really braces it up.

Even get a discount on USPS "flat" rates

I flip traps for fun both users and collectors as well as collect ATC/victor duck decoys. I use flat rate and ship station and ship from Alaska. seems more reasonable than what a lot of the guys shipping other methods to me are paying.
