I know what you mean! My husband and I both applied for Kay because we knew that it gives out high limits and increases your score. We were approved for $4k limit each. Now I'm trying to figure out how to even utilize that card, as we are saving as much as we can.
With other general cards (VISA, etc.), it is easy to redirect your monthly bills through it and pay in full. Even with Target I can redirect some of my grocery and clothing expenses.
But with a jewelry card...I just don't know how to use it effectively. We don't really have jewelry in our budget over the next year. I have $100 each for my children for Christmas...but only two out of the seven kids are girls. The boys aren't likely going to want jewelry for Christmas.
Congrats on the new card!
