I have question about installment plan.
If my cc credit limit is 5k, the item that i want to purchase costs 6k, i'll buy it under installment plan provided by the retail shop, can I call the bank to increase my credit limit temporarily to make this purchase?

why do you judge others? is that going for installment plan over limit = going for debt? how do u know that someone doesn't have enough saving backup just because they have low credit limit? how do you know that someone will not pay up just because they have low credit limit? or u think low salary person mostly will not pay?
why do not u think that i use installment plan because i plan for unpredictable needs? if i have 6k+ saving enough to buy the item, today i spend it all to buy the item, and tomorrow accident or get sick or whatever (touch wood) and need huge sum amount of cash, but i've got no saving anymore, what would u do if it were u? die alone? worst case eventually u'd go for debt as well, worse than buying sth over credit limit. (Do accept my advance apology) <- eh no don't accept when it already hurts
