Hi, I had this in the cart to buy. Then when I went to check out, it showed as the only shipping option "curbside delivery" for $28.50. That is nearly half of the item itself.. Is there some sort of error here? I won't order the item unless there is a more reasonable cost for shipping. My plan was to start by getting one, and if I liked it, order more for a project. Let me know about shipping, as I will only buy if shipping is affordable. Thanks
