need help guys, possible ebay problem here?

[Dropt72Shortbed]

i bought a tach/air cluster off ebay a few weeks ago.

I paid and the seller left feedback and said the item was shipped on 5/12. it is 5/29 and I haven't received anything yet.

I paid extra for insurance which was a good idea. now its been 2.5 weeks and no item has arrived.

what is a reasonable period to wait before asking the seller to go to the post office and check things out? 3 weeks (that will be in 4 days) for shipping, its just a box the size of a guage cluster going from indiana to california, anything over 3 weeks seems pretty long to me, no?

i paid with a money order and kept the receipt so if i have to file for fraud with ebay i guess im ok, id just rather get the damn thing and not have to go through the hassle of working with ebay.
