Dont take my comments the wrong way:) I'm just tryin to help. You can ship anything that weighs 13oz or lower in 1 of those bubble mailers. I ship stuff on ebay all the time. Its only 1.93 for small items all the way to 5oz. Every ounce after that is a few more cents. Hope that doesnt confuse you
If you would have shipped them together in a small bubble mailer envelope and shipped them FIRST CLASS it probally would have cost you about $2. Dont worry. I've made the same mistake. Lol
