The Only place that I have found that actually tracks your Membership Card is Costco ! We don't have SAMs Club in Canada so I can't comment on them!
All these other Discount Membership cards are a Joke! Many if not All Auto Parts Stores , RV Parts Stores and even Mechanic Shops offer Anybody that walks in and asks a Discount!
Anyone who doesn't ask is losing out! The same applies to Every Consumer Item of Merchandise and or Service including Meals in Restaurants!
If You have Grey Hair ..Seniors Discount!
If You have A pleasant Smile ..Welcome to Our Store .. Discount!
If You arrive Early Discount!
Arrive Late Discount!
Just Ask! Discount!
The problem is Somebody has convinced Most Every Retailer to Advertise in The Book!
Here's how it works! I have been there first Hand!
Salesman : Advertise with Us and offer Your Flood of New And Regular Customers a Discount!
C G O But How will I make enough margin to be profitable?
S. just Jack Your Rates UP by a Third.....Then offer A 10 Percent Discount!
Now that strategy will actually work for quite awhile . Until everyone buys into the same program.
At that point Either everyone is out of business !
Or The Market Share of those with the Most Clout gains control of the Entire Market !
Sounds like the same old story to Me!
