This sale doesn't start until Monday.

I went to her website (eleanorburns .com) to order a triangle square up ruler. I was going to order the 6 1/2" but then decided to order the 9 1/2" since it is also on sale. When I clicked to calculate the shipping it was $9.47 FedEx ground and $18.20 1st Class/Priority, the ruler only cost 8.97! i decided to compare other shipping costs for similar items - 16" Square Ruler cost was $12.57- shipping was $8.36 FedEx Ground and $9.00 1st class/Priority. This doesn't seem right. Is anyone else experiencing the same results???
