No you only buy the coupons you want and how many of each you want. Just as an example today I bought 10 coupons for $1/1 quaker oatmeal and 20 coupons for $2.25/1 finish tablets. These are higher value and popular coupons, so they were a little more expensive. I paid .15 each for the oatmeal and .20 each for the finish tablets plus .94 for shipping. I typically don't use even half of the coupons in my newspaper, so purchasing only the ones I want ends up saving me money. She ships them from Texas first class the day you buy them. So it usually takes 3-4 days for me to get them. I on average spend $4-5 for coupons each week, sometimes less sometimes more. It just depends whats on sale that week
