Here's a little math I did based on the three racks of spares I did last week:
Rack #--Price/lb.--Wt.-----Net Wt. After Trimming
1-------$1.69------3.97----2.06
2-------$1.69------4.21----2.12
3-------$2.29------3.62----1.81
Yes, literally half of each pack's weight was scraps packed under the racks or what I trimmed off myself. So, for each of these St. Louis-trimmed racks, I paid $3.26, $3.35, and $4.58, respectively, per pound for the privilege of trimming them. This week, I took a closer look at the spares at the high-end grocery I frequent for the extensive wine selection-- they had already-trimmed spares on sale for $2.69/lb, and no scraps or breast bones buried under the racks in the packs. /infopop/emoticons/icon_frown.gif
