We were able to order our UppaBaby Vista at Bed Bath and Beyond this weekend using a 20% off coupon. (yes, the fine print said it couldn't be used for Uppababy) Thanks to the previous posters who have shared this approach, it saved us $136!
The details: we went to the store to place our order with coupon in hand. We decided for the potential savings it was worth taking a chance. They didn't even read the fine print and also asked if we've found it anywhere cheaper because they were willing to price match. We did opt to pay shipping for the ease of home delivery.
FYI, I hadn't received coupons in the mail from BBB in months. If you register on their website, they electronically send you a 20% off coupon for a single item. Beware, it does have an expiration date of 2 weeks in the future.
Hope this is helpful for anyone considering an Uppababy!
