Janina I have not experienced it myself but people have had trouble with their tires/wheels getting very squeaky. The most specific I read is the outer and inner part of the wheel seperate and the "tire" moves without the wheel and this squeaks? I don't know for sure. Have not seen it first hand. The wheels are plastic with a thick outer foam part. The new ones are supposed to be more of a "one piece" design so I guess you won't have the seperation and squeaking?
I'm not sure how much it will add to the push of the stroller. Waiting on reivews from someone who has had both.
as for the promotion - I guess the store that listed it wasn't supposed to list it yet. Basically you were to create a baby registry and list one thing from each of 5 categories. There was a stroller category, a car seat category, a large accessory category, a small accessory category, and a baby carrier category. All Bob or Britax stuff. You had to recieve each item from the registry (I guess it had to be bought at that store) and then you had to mail in the UPC from the boxes and then you got a free blvd 70.
It seems like a promotion that targets a very specific group, ie the first time mom who has nothing... most people aren't in the market to buy that many big ticket items at once. (The Britax strollers were the B-ready or the b-agile DOUBLE, not single - then all Bob strollers) So MAYBE it's a good deal if you were gonna buy all that stuff anyway, but for most people, it's not a helpful deal IMO.
Not to mention it prevents comparison shopping to get the best deals and/or buying stuff used which would both more than add up to the cost of a car seat, in many cases.
Can't say I am impressed by this particular deal.
I expect it will result in a glut of "new in box" blvd70s and britax baby carriers on ebay and CL in a few months.
