Being an eBay Powerseller for years we were tired of getting gouged on small shipments with Canada Post led me to a lot of frustration in finding a box that is JUST under 2cm deep in order to fit through the infamous Canada post slot. Because this will qualify your shipment for cheaper LIGHT PACKET or LETTER POST rates which are usually at least 60% less then the SMALL PACKET rates if you use a box over 2cm thick !
For example: if you were to ship CD case, jewelry, hockey cards and use a box that is over 2cm thick you automatically have to pay SMALL PACKET rate of $5.97 to USA (even more for Air service) but with our box it would be only be $2.10 since it is under 2cm you get the LETTER POST rate ! So you would save $3.87 on this shipment alone... now, if you ship a lot, then the savings are staggering !
See rate guide for comparisons. With our box the more you ship THE MORE YOU SAVE !
