Where Can I Get The Boxes To Mail My Entries?

I get them from Dollar General, Different sizes for a few cars to a mess of them.

I use bubble mailers most of the time.

I've mostly been using the free flat-rate boxes from the Post Office since I usually pack a few Matchbox or Hot Wheels cars as a contribution to the prize pool. I can fit 4 carded cars and one or two cars for racing in the box with plenty of room for bubble wrap or other packing materials. You can use my box that I sent you as an example.

I sent this one to another race but it shows the way I pack the box.

Bubble mailers and snack containers from the Dollar store...they work for me...

I ask at the grocery stores for tiny boxes, it's  hit n miss but I usually don't have to buy them very often

I get mine from a lot of things - my mom's packages, work, etc.

I get my boxes from Uline, ordered from their web site, and since I send cars 1 or 2 at a time, the 4x7x2 size works for me. Bubble wrap I get from places like Staples, or any place that sells office supplies.

My wife orders a lot of small items so I just re-use those box's and fill empty space with packing paper.

Are we speaking of the outer box where shipping labels go, or the inner container holding the actual car, because the first is relatively simple, the second a more complex topic

Dollar Tree snack containers with locking lids. You can get them in packs of 2 or 3. I wrap the cars in bubble wrap and you can fit one or two cars in a container. Then I just put it in a bubble mailer.
