I know alot of us end up mailing Host Packets and such, and it's not cheap. (I'm hoping this year to do less MAILING and more delivering- either at shows, or in person).BUT, if you do still have do it via mail now and then, one thing I've recently discovered is much easier, is to just Send them Priority Flat Rate Envelopes. You can go online to the Usps.com and in their store https://shop.usps.com/webapp/wcs/stores/servlet/CategoryDisplay?storeId=10052&parent_category_rn=10000002&categoryId=10000033&top_category=10000002&langId=-1&catalogId=10001- select the Flat Rate boxes/envelopes. You can get them for FREE- they'll ship to your door!! You'll get the envelopes or boxes or whatever you prefer. Priority Flat Rate Envelopes cost $4.75-$4.90 to ship. If you purchase and print your shipping label online- it costs $4.75. If you buy it at the Post Office- it's $4.90 (plus the hassle of going to the post office). Just create an account on their site, and then you can buy and print online! Save time and a little money...plus your host gets her stuff in 2-3 days!I print mine on regular paper and just tape it to my Flat Rate Envelope and stick it in the mailbox (or by it). You can also schedule pickup of the item (during the checkout).Wasn't sure how many knew this feature with the USPS, but it's handy and saves me a ton of trips to the Post Office!
