Based on our experience both on the laundromat side & the car-dog wash side ... when it comes to ordering it pays to be organized on our end in terms of having space reserved for larger quantities.
Timing can be important ... watching & acting on the $1250 minimum order KR's Trade Show Special Rates ... KR tends to become the best option.
As far as different rewards programs ... I have mixed feelings. We get a bit tired of wasting time with a wide array of what I call "bobbing for apples" reward prizes ... Verizonwireless UP is the latest for an unpleasant experience. My bank's reward prizes is another unpleasant waste of time IMHO. Another is Kellogg's products. Don't get me started about
credit card "tease" sign up offers. For an honest disclaimer on my part ... I am not sure about other's experiences with rewards prizes though ...
It seems like some suppliers cater more to the largest corporate buyers a bit too much. That scares me a bit with big oil companies affiliated with such an overabundance of gas station automatic car washes.
