be forewarned that is you make a return on that Disney Visa card within those 6 months.... that credit goes against the 0% balance.
For example.
This month u charge only a disney vacation for $1000. You get the bill for $1000, but dont have to pay anything as its 6 months interest free.
Next month you buy a $50 item and then return it. Your bill will be $1000, but only $950 will be interest free for the remaining 5 months... and you must pay $50 to avoid finance changes.
So the lesson here is dont buy stuff on the Disney card you are likely to return if you are carrying a 0% balance on the card.
