They helped me get to the quarter million dollar club. 
I'll be honest, and since I'm not a politician......I have such padding to help my utilization. You can take that to the bank!

@I used to have two store cards, Sam's Club @ 3000.00 & Sears @ 900.00 CLs. Sam's started at 3000.00 about 25 years ago. Sears was initially at 800.00. I've never asked for an increase on Sam's but a few years ago, I needed a new appliances and wanted to get them from Sears, just to use the card and because they had 6 months SAC. I requested a CLI and they increased it by 100.00, bringing the CL to 900.00!!!. I went to Lowes and applied, got my appliances, along with a very nice CL. I paid off the balance before the 18 months promo ran out.
It annoys me that I took the HP for 100.00 increase but in the end it worked out. Sears lost & I won. I will never request another CLI on that card but I do use it fairly regularly. The CL is quite adequate for the small charges I put through it. When I have big spending, I'll go to Lowes.
YMMV with every card. Maybe in your case because Sears is backed by Citi and Lowes Synchrony? I had a JC Penneys card from 1994 and they never granted an auto CLI. It seemed like every othe card was. When I did ask, my CL was increased by $200 to a whopping $700.
Now just don't go crazy in the sock section!

I took my Brooks Brothers card out my "sock drawer" (a bedside organizer)...to buy socks (and save $20 on them).
So even when I use it, it's a sock drawer card!
