I had an auto CLI from Cap1 in (I think) January, and just found out today I've been auto-CLI'd by GEMB (Banana Republic) - not sure when it happened, I only just noticed the new limit showing on my credit report. It was only a tiny one (from $500 to $600) but oh well - given that I've not spent any money on the card since I opened it in December, and given that it's had a zero balance since March or April, I wasn't expecting (or planning to ask for) anything.
My husband's had generous auto-CLIs from Target and BoA in the last couple of months.
