Nobody seems to answering you want this so:

0% installment meaning you could opt to pay your certain credit card purchase in installment manner without interest charge on you.

Mostly all cards have this feature, but you better double check.

No, they don't have to partner with retail outlets. You just need to call up your credit card service after you made the purchase, and tell them you wish to make it an installment for the purchase you just made.

But some banks may have an amount range that entitle the 0% interest. Any amount outside the range may charge you a little interest upfront. (1~3% maybe).
