The last time I ordered from Marco they threw in an extra t-shirt and shipped less than ten minutes after I placed the order, showed up in two days.
Pinball life shipping seems like it's generally more for some reason and last time I ordered they didn't actually get it out the door for four business days. They are cheaper for commodity-type things like bulbs though. I don't think $5 is worth a week of waiting when I'm placing a $50-$100 order.
