Great news, Sue!! Thanks for the update
I understand your conundrum about the products from other places. When it comes to the tools, I think it's important to recognize that you know they can buy some of them elsewhere with coupons, etc. I would focus on the fact that purchasing from SU will help them earn credits and also that because SU sells these products they have the benefit of you being there to support and help them in using the products. Kwim? Even if they purchase them elsewhere, they need to consider you a resource, too. I think the goodwill goes a long way to customer loyalty.
Also, you can focus on the products SU sells that are compatible with those tools - you may not get that one purchase from them, but you can build on it. And I'm pretty sure SU has quite a few exclusive products so I'd focus on those.
It's crazy in this day and age to bury your head in the sand and try to pretend you're the only store out there. But you can work with that fact and turn it into a positive.
Hope that makes sense! (It sounds better in my head
I wish you much success!!
