Redflare - I was thinking about ordering one or two of these from your site. I have a question on shipping rates. You have $1.99 for 1 lb or less. Is this calculated on the item weight shown on your website or on total (boxed) weight? Specifically, these bivies are listed as 0.25 lbs. Does that mean you'd ship three of them (0.75 lbs) for $1.99 total? I imagine the boxed weight of even one would exceed 1lb, depending on the box/packing materials you use. -- Thanks
