While there have been plenty of congratulations in this thread and I hate to be the one to take a different (and possibly negative) angle on this, I feel I must.
If my math serves me correctly, the OP has 11 total cards, 9 of which are store cards. While having a couple of store cards is no big deal, having 82% of your cards being store cards, many with tiny limits, is actually a very poor "look" when it comes to revolving credit. While it may not be a big deal now, down the road it certainly could be when the time comes to apply for prime cards. The OP mentioned wanting to buy a house in the future and also mentioned a bunch of negative profile history. Adding more and more store cards to that profile IMO is only going to hold it back more going forward, not actually help it.
Getting approved for a store card with a $150 limit isn't a good thing; That limit is a warning sign that you shouldn't be applying for anything right now.
I would strongly advise against opening any more store cards and would actually recommend closing some of them at some point in the not too distant future.
