[quote name='GBAstar']If it weighs less the 13oz it can go first class regardless of what medium you use to ship it (bubble mailer, box, envelope, etc.) pick a method that is cost effective as well as durable enough to protect the game.
Most standard games will do fine in a bubble mailer. Don't mail valuable games or CE's in one or anything else where condition upon arrival matters because your buyer will be angry if the item arrives damaged.
You won't find any free supplies on the USPS website for mailing first class items. The free boxes, envelopes and mailers they provide are incentives to upgrade your postage to either Priority or Express.
If you're going to mail first class find cheap mailing supplies. You can buy in bulk through amazon or discount mailing supply stores. Personally I use mailersusa.com. I buy the poly bubble mailers "white" #1 size (7.25" x 11.25") and they will accomodate any normal size DVD, CD, Game, etc.
I think they are $19 for 100 which isn't the best price I've seen but it is still good. Anything less then $.20 per unit is a reasonable price.
I prefer the white poly bubble mailers just because they are more weather resistant then the kraft yellow mailers (what AZ uses) and they are also less rigid so if you buy the larger sizes you can actually wrap them around the game one or two times for more protection.
Also as far as first class 1 2 and 3 oz is the same rate. If you print on eBay it will cost $1.64 with Delivery Confirmation (DC). I believe 4oz is $1.81 and 5oz is $1.98. Price goes up with each additional ounce. After 1lb the price only goes up by each additional pound. Remember if something weighs 2lbs 0.1 oz you are supposed to pay the three pound rate.
Also, and this should go without saying but you're paying postage on the entire package weight (item + packing materials) not just on the item weight.
A good rule of thumb is most standard games weight 5oz (PC, Wii, 360, PS3).
Some will weight 4oz (some PC and 360 due to the cases being thinner material) and some will weigh 6oz if the manual is thicker or there is a second disc.
Some Vita and 3DS games only weigh 3oz.
This is improtant because you need to factor in shipping costs into your profit. You can charge seperately for shipping in your listing but I build it into my price for a few reasons:
1) you get better visibility on eBay item searches if you include free shipping
2) with many retailers offering free shipping buyers expect it
3) by offering free shipping you automatically get a 5 on the your shipping price DSR (DSR are detailed seller ratings on a scale of 1-5). Currently you need a 4.8 or better to be top rated and I think anything under 4.6 is below standard and could result in your accoutn being closed)[/QUOTE]
Wow, you totally know your shipping
