Dynamite Canada is offering free shipping on all orders with no minimum until tomorrow, December the 16th. No coupon code is necessary, so if you have code from the loyalty program you can go ahead and use it. Sale items are an extra 30% off the lowest price right now, just be careful as some are marked final sale.
There is also a gift card offer at Dynamite that is valid until December the 24th. Purchase a $50+ gift card now and you will receive $10 off later. You will be sent a digital coupon from January the 1st to the 15th. If you are going to purchase a gift card you have the option of ordering a physical card or sending one by email. You do have to be a loyalty member in order to get the $10 bonus, and you can easily sign up first.
Although Garage is not offering free shipping the moment, don't forget that your Garage and Dynamite carts are connected through the apps, so if you add Garage items and check out through Dynamite you should still be able to get free shipping.
