Dollar general has a sale on ludens cough drops. Buy 4 save $5. Plus stacking it with the $1/2 luden mfc made them free!!(kinda,sales tax)
Break down:
Buy 4 bags at 1.50 ea. =$6
Minus the buy4 save $5= $1
Also taking off coupon -$1/2=free!!!

Amazing sale wish I would have known sooner! I paid .13 sales tax for 4 bags of 20 ct. Bags(:
