ive always done all my rc shopping thru the monster with amazing service. on tuesday around noon i ordered a set of p2 rockers and opted for the usps express shipping. (overnight) it is now Thursday and i still haven't received the parts i ordered. i checked tracking and i should receive them by tomorrow. the part that im not comfortable with is that i payed an additional 20$ for the overnight shipping when its taking almost the same time to get here as the 5$ shipping... tomorrow morning i will call usps and see if this was there fault or a monster issue
