Helping the summer slump

Looking for suggestions for boosting sales during the June/July months. We have a great turn out for our Wellness Wednesday promotions (first Wednesday of every month) and our owner discount days, but when the colleges let out and all the families go on vacation, supplement sales tend to trend downward, bodycare sales remain steady or even increase. Looking for ideas for demos, exciting new products, or just all round good advice Thanks for any and all suggestions. Be well! Matthew
