Best to check first though if it will be a bargain for what you are hoping to send. Saves trying to pack something up at the post office. Try to keep at least 1 on hand at all times. I've been using more often too as of late. I thought it was interesting that buyers not only know about the boxes but know the price! One even knew exactly how many Barbies fit into one! One of my repeat buyers in BC also asks me to use them so I better have them on hand. I've actually started having a few people in other provinces ask me if I would use one, one even telling me the price! She thought it was $18 (rounded down and didn't add the tax) but little bits add up, after all the $2.46 tax difference becomes $5 by the time the eBay fees for the box come in to play!). If you use stamps or any other Canada Post product they can be ordered in the same way, as can coins and other collectible for the heads up I will have to get a few more. Preferably go and make the order during the day when it's more likely that a manager will be present part-time staff may struggle with processing the order as it is an uncommon transaction. If you want to do this just go in and say you would like to make a 'Direct Ship' order for flat rate boxes (or they should know what you're talking about if you say you would like to order some flat rate boxes to be shipped to your home). If anyone has a paraticular affinity for the folks at their local CPC outlet you would be helping them out quite a bit if you placed an order in person, as Canada Post's 'Sales Focus' (a sales target goal that post offices try to meet) for the months of March and April is for processing a certain number of in-person orders from customers (called 'Direct Ship' orders). Or, you can place an order directly at any Canada Post location, pay at the counter, and your order will be shipped to your home or business. If your local post office is out of stock they can be ordered directly from canadapost.ca in cases of 12 (free shipping applies for all orders over $25). If you regularly use these boxes it might be beneficial to stock up before Monday.
