WELL, I've wasted my night stressing over this, and I just pulled the trigger and bought the new BOB. I think mine should easily sell for $250 even though I listed it for $300 with the carseat adapter I have the doesn't fit my carseat. I found the new BOB priced at $321 tonight on Amazon, and our account had a $15 off coupon, so I bought the brand new one (that's $400 elsewhere) for $300 shipped. You know how prices fluctuate on Amazon, so I was worried that if I waited, the price would go back up. Plus we have the Amazon Mom thing that gives free 365 day returns- so if my stroller happens not to ever sell, I can ship the thing back for free.
PLUS- I found this
Registry Rewards - How it Works - Britax USA
We needed to buy DS a new seat since his expires in 2013, and the carseat adapter and a cupholder are the other two things we'll be buying anyway, so there's only 1 thing on the list of eligible products that we weren't planning to buy before the April 1, 2013 deadline (the carrier). I'm pretty excited to be able to get a free Britax Boulevard for this little guy's next seat by spending an extra $70 (and maybe reselling it for a little less so that it's not really that much out of pocket if I'm lucky enough to get that to work!). That's a big $320 purchase we won't have to worry about a year from now if this all works out.
Anyway, lots of if's, but I'm at least feeling less panicked about not having a stroller that would work with Bub's seat that we already forked out $200 for and can't return!
P.S.-- DH is really loving me for coming in at 1:45 AM and waking him up to make sure he was on board. LOL. I got the typical "do what you need" response, but I would feel terrible not at least discussing it a little before I purchased it, even if it's returnable.
