Just got my Amazon Store Card in November, a little over 3 months ago. Nobody has been giving me any love with CLI's lately, last one I remember getting was a tiny one from Cap1 like 18 months ago.
Hit the love button today on a few different cards, nothing from any of them, then I thought "what the heck, let's try Amazon." Existing SL was $3800, I asked for it to be $5000, and was insta-approved. Sort of makes me wish I asked for more, lol!
Datapoints: scores (roughly what's in my signature below, though I haven't updated it in a bit)
Overall utilization across all cards: 40%.
Utilization on this card at time of request: 84% 
(Don't worry, I don't actually carry that much credit card debt, I just put a LOT of spend on my cards every month)
Total Loan Balance: $43k / $65k
Total SL: $78k
Congratulations on your CLI!
Grats on your Amzn Synch cli 
Congrats 👏 on the Amazon CLI!
Congrats on a nice bump. Always go at them for the 10k!
