I thought Stars checks over 1k are sent via Courier

[JamieO]

I hadnt ordered a large check from stars in awhile, but the last one over 1k i ordered was sent via regular mail. It took 13 days. I thought it might have been a mistake, so i didnt think much of it. I just ordered another one over 1k, and its been 8 days i dont think its coming via courier. Is this normal or should i complain to them?
