National retailers that don't accept American Express
Please reply with ones you know of and I will add them to this post, so other RFDers can have a resource.
As a matter of note - I have never been to an national chain eat-in restaurant or gas station (so far) that did not accept American Express...
*Update* Smittys is one!
*Update* Removed Tim Hortons and McDonalds and Subway since they now take Amex. Added DQ. Removed Zellers since they are shut down.
Here are ones I have made note of lately:
Real Canadian/Atlantic Superstore
No Frills (Mastercard only)
IGA (conflicting reports)
Starbucks (some locations reject)
Second Cup (some locations reject)
KFC (some locations?)
Arbys (mc only)
Canadian Tire (some stores reject. All gas bars take Amex)
Insurance / Finance
Google Play Canada
Home hardware (some locations)
