i think it's a great deal too!! especially since their shipping is free...my inital thought was that was where they got you. but seeing how it's free, i would say it's a good deal.
i'm not sure how you intend to ship your boxes, but you might be able to contact a local shipping company (United, Allied, The Packaging Store, etc.) and see if they have any suggestions. if you are going to use a shipping company where it doesn't matter what is on the exterior of the boxes, just as long as they are labeled correctly (name, address, phone number, etc.)...you might consider going to a local grocery store and asking them for boxes. then you would just need to get the tape, and bubble wrap...which would be cheaper than $43.
i was able to get all my packing stuff for free cuz one of my friends works for a packaging company. i'm not sure how close/far you are from lombard, IL, but there is a division of her company there (
www.landsberg.com). i would be willing to bet that you could probably get free boxes from them if were a bit creative.
