Actually, it would be better if you can specify which type of double stroller you are looking for (side-by-side or front-back or front-bottomtype)...
I wanna sell mine... It is Contours Option Tandem lT bought at $589 in Jan 2013. Front-Back Type... Both side can recline fully & detachable... both side can also be placed facing each other even when fully recline...
Usage: Max of 1 time per week since purchase
Condtion: Still great as it is very durable. Only load it in car when we need to use. Else, it will be stored at home.
Price: Not fixed. Maybe you can share with you what is your acceptable level if you are interested.
