summit racing shipping question

I ordered a part yesterday from Summit, and I paid the extra $12 for "2nd Day Air" and I was wondering what exactly that means. My car is not driveable without this part, and its my daily driver so I'm sorta in a crappy situation right now.

Since I ordered it on Saturday, it should ship on Monday (correct?) and should be here by Tuesday(??). Or Wednesday!? I HATE not having a car!:bang:
 
Wednesday, but they use UPS. It usually takes 2 days for me to get stuff way up here. They are usually very efficient in shipping. I think 2 day shipping is the norm. You in Mass. should be included. Try it next time with regular shipping and see for yourself. Might save you a few bucks down the road.:eek:
