B.rian covered the bit about the auction being over.
It's standard eBay rules which mean you enter a maximum amount you're willing to pay (i.e. $50) and eBay automatically does the rest. In short, even if you enter a maximum bid of $50, if the next highest bid is $20, your bid will only be $21. eBay automatically incrementally increases your bid up to the max ($50 in this case) as others bid, until your max bid is surpassed (in which case you'll be notified and have an option to increase it), or the auction ends and you win. It's really pretty easy and hands-off (the automatic increases mean you don't be by your computer as the clock winds down since you can't see anyone else's max bid and they can't see yours- no last second snaking). If you have a paypal account linked I think that as long as you set "local pickup," you don't have to do anything after it ends.
LTR sets a flat shipping rate across the U.S. ($45, I believe), but there's an option to pick up at the store for free. You can select that when you pay. I see you're in Falmouth, but it's worth it to make the trip up to LTR to see the store. It's really pretty nice.
