Need SPD staff to use the Manage Variations page, http://spd.justmagicdesign.com/admin/commerce/product-variations, to double check all the details of the products, like dimensions and weight.
In particular, from Jen:
I estimated the dimensions of the Piping Hot Cording based on the picture. I'm also not sure that the weight is correct. Donna (or Sue), would you please double-check the dimensions and weight for this product and update as necessary?
