The best solution instead of paying a "few dollars more" for 2nd day is to join the Team performance. Costs $20, but you get free 2nd-day shipping upgrades plus a 10% "rebate" on everything purchased.
As for ordering on Sunday and it not being here yet: Monday was a holiday, duh.

not sure why they said it would ship. They have until the end of the day tiday to get it to you and they will. Haven't failed me yet!
PS On the Team Performance thing, I paid $20 in July, have saved $40 w/ the 10% back and have received 15 packages w/ 2nd day shipping for the regular shipping price, not to mention 2 "members only" sales where I saved an additional $15. It's worth it if you order a lot. They'll also match Nashbar's prices if it's the same item... The Team P savings are on top of coupons (when they have them, which seems rare)
