We like to keep things simple, so Faders Music Inc. offers Free Canada-Wide Shipping for almost all orders over $99.99 (before tax).
Local customers may choose to pickup their order at the store free of charge during the checkout process (click & collect). Free local delivery to Brandon, MB addresses is also available for orders over $25.
Here's the thing... some larger/heavier items may be subject to shipping charges. Canada is a big place and shipping companies calculate their rates using "dimensional weight" meaning larger items are very expensive to ship - even if they don't weigh very much (i.e. an empty guitar case).
We want to be completely transparent with our shipping policy, so here is a list of items that we have to charge some shipping on. (these fees usually work out to about 25%-50% of what we actually pay).
Faders Subsidized Flat Shipping Rates (within Canada)
- 61-76 Note Keyboards : $39 + tax
- 88 Note Pianos : $89 + tax
- Electronic Drumsets : $49 + tax
- Empty Guitar Case (hardshell) : $39 + tax
- Guitars < $350 Value : $39 + tax
- Amps 25+ watt : $49 + tax
- Guitar & Bass Bundles : $49 + tax
If you make a purchase from one of the listed categories and choose Free Canada-Wide Shipping, we will email you a secure link to pay the shipping charge after you've made your purchase. It's super fast and super easy.
Note: Some remote or rural locations may be subject to additional shipping charges. For example, if your delivery address is a PO Box and you order a large or heavy item then we will email you a secure payment link with a subsidized flat rate shipping charge determined by the item(s) ordered and your delivery address.
A brief note about shipping & delivery estimates:
When you place an order with Faders, we always ship within 1 business day (same day whenever possible). In short.. we inspect, pack and get it out the door as fast as humanly possible. Place your order on a Monday - it leaves Tuesday at the latest, place your order Friday at 7:30pm CST - it leaves Monday morning etc.
Once your order has left the store it is in the hands of the delivery company. Shipping estimates shown in our checkout process are estimates provided to us from the shipping companies - they are not guaranteed delivery dates as there are many factors which can impact actual delivery times such as: seasonal shipping volumes, extreme weather, staffing/technical/mechanical issues, delivery location and global pandemics (occasionally).
We do everything in our power to get you your gear as fast as possible & we know the shipping companies are working hard to do the same.
If you have any questions, please send us an email info@faders.ca or chat with us here on the website.
