I ordered two maps - a state map and a city map. I wanted to first get them delivered to my place, so I could personally ship them out to my family overseas so they could take a look at the maps while they planned their trip to visit me in my state. It took exactly two months from the order date for these two maps to get delivered.
Within those two months, I got tired of waiting for my Omnimap order, so I ordered the exact same/similar maps from Amazon, which arrived at my place in three or so days with no special treatment from Amazon, I just chose the cheapest shipping option. Then, I mailed those maps abroad to where my family lives and they received that shipment, which was by SEA, about two weeks later. So it took less time to do all that, than to receive two maps from Omnimaps in North Carolina.
I can see that Omnimaps may pull through eventually, but you're going to have better luck receiving your maps in a timely fashion if you search a bit harder online or go to Amazon.
