Is it just me... or has anyone else noticed how ridiculous USPS flat rate boxes are?? The biggest box (literally) was "MEDIUM" flat rate. The "LARGE" was thicker but smaller at 12x12. And not only that... at 13-5/8" x 11-7/8" x 3-3/8" their biggest flat rate is just enough to jam a 15.4" in... without any packaging! It was like they were playing a trick on us. Well not anymore. USPS has changed their flat rate lineup. There is a new large box... with dimensions of 23-11/16" x 11-3/4" x 3". Still only 15$. Just measuring my 16:9 17.3" laptop, it will fit with just enough room for packaging. There is a 20lb weight limit for international. The funny thing is, of course they aren't offering it for used laptop sellers... Get this: Anyway. Heres the link: https://shop.usps.com/webapp/wcs/st...viewAll=N&rn=CategoriesDisplay&WT.ac=10007423 This is great news for international sellers, at only 35$ to Mexico and Canada, something like 60$ everywhere else, and you can get it insured. Up to 20lbs. None of the post offices will have these right now, so you have to order them, but they're free. Not trying to advertise for USPS or anything. This is definitely the most cost effective option for 5 day in many cases, I guarantee you that.
