Yup - same here.
On my recent order there were out of some fittings - I got an email from Brenda as follows:
"Thank you for your order. (2) 2703LN-06-06-06 (2) 1501L-04-04 are BACK ORDERED. Those parts should be in within approximately 4-5 business days. Let me know if you would like for me to ship what I have today, cancel these parts or wait for this order to ship complete. Please note that there will be separate shipping charges if shipping partial."
Since I wasn't in a big hurry, I told her to go ahead and wait to see if they came in in 4-5 days and if not then just ship what she had and cancel the rest ... I would source those locally.
This was the reply I recieved back:
"Okay I will ship the order complete and will keep you updated,Have a great day."
Three days after that I received notice that the order had shipped, complete.
AFAIC, they're good folks to deal with ... although they are not always the cheapest on some things.
