The low Reseller rating doesn't surprise me. There are only 210 reviews (not all of them are negative), and they go back to 2004. Cabela's is a massive, bi-national (at the very least) company. Those 210 reviews don't even amount to a drop in a bucket, and people are much more likely to post a review if they're PO'd about something. I think it would take thousands of negative reviews to indicate an actual problem. And, to further confuse the issue, the location of the reviewer isn't posted that I can see. I don't know if they're Americans or Canadians.
My parents came to Canada in the 1960s from Scotland, mostly for the hunting and fishing opportunities this nation offers. The Cabela's catalogue was our coffee table book while I was growing up. Dad ordered from Cabela's US (before they expanded into Canada) often, and without trouble or hassle.
Now, there were issues when Cabela's expanded into Canada. The service was still mail-order but they had a warehouse in Winnipeg. It could take months to have an order filled, and there could be lots of run around. This issue wasn't Cabela's alone. The same issue existed with another Canadian retailer, so I suspect a lot of it had to do with our draconian firearms laws and general supply issues. There were many of us who were frustrated, and unhappy, and chronically complaining about Cabela's. How many of those 210 reviews are from Canadians who were struggling with the frustrations of the Winnipeg warehouse?
Cabela's now seems to have worked out the kinks on the Canadian end. There are a now nine retail stores, which are stocked pretty appropriately for Canadians. Target should have taken lessons from Cabela's. And, BassPro is still trying to sort out stocking issues in Alberta at the very least (we don't have bass in Alberta, and turkey hunting isn't big on the list, so why are the aisles full of bass lures and turkey hunting gear?), when they've had a big Canadian retail location open longer then Cabela's has.
So, to sum up my wordy post, I think Cabela's is a now great retailer on both sides of the Canada/US border (for shopping in the store and for mail/internet order . . . which I personally do both of). For your purchase experience to not be satisfactory would not be the norm, IMO.
