C/W Carefree Sunblocker 6'X15'

First let me say this is NOT a complaint.I'm asking out of curiosity. I went on line this morning to check out their Sunblocker screens and while the DW and I were in Lake City Fl.this afternoon I stopped by the C/W store and purchase one.I paid $108.99 for it, however when I got home I checked my emails and there's one from C/W titled "WINDOW SHOPPING" and there's the picture of the sunblocker I just purchased, it's $132.16. Below is a picture of the same sunblocker and it's $100.77 and to the right of that is another picture of the same sunblocker for $101.24 and the last pictured one to the right was $94.67. All were the same item available in four colors and same size 6'X 15' but (5) different prices in the same sale ad. "WHY"
