Hmmm. You aren't getting any response here. I am not sure the best place to move this too, but I think we will try the Tips board. Maybe some over there can help you with this question.
Because we only had carry-ons this trip I decided to ship my fragile stuff home. I had 3 mickey head ornaments & 2 containers of garland. The total came to $45. I received it the next day-no damages. I wasn't too thrilled to pay that amt. but they probably would have broke on the plane so it was worth it for me. Went down to the Bou-tiki 9/1 (Labor Day) in the afternoon and arrived 9/3 in the morning!!
In 2006 we went on a land & sea package, so I had souviners shipped from the store where I bought it, home. It was great! It didn't take that long, I think about 3 or 4 days but it would depend on how big of package you were sending.
I believe shipping costs depend on the total purchase amount. I had things shipped home from F&G in May and I think if was $9.95 for up to $50 and then went upwards from there. I had 5 Mickey gnomes (one was for me and the rest were gifts) sent home with a couple of sets of mugs and if I remember the shipping was $22. There was no way I could of got them home any other way on the plane so it was worth it. One set of the ceramic mugs were broke but I called guest services and a new set was shipped out right away at no charge. It is a great convenience shipping what I buy home and always fun to come home from work and find a package there!
