Actually, "St" isn't a typo for "Street" in most shipping systems - USPS and UPS both accept "St" as the standard abbreviation. The system probably would have sorted it fine without the change. But yeah, that's still brutal. I had a similar thing with my phone carrier where they kept bouncing me between departments just to add a second line. One agent asked me to reset my network settings which wiped all my wifi passwords for no reason. Sometimes I wonder if these companies purposely make it harder than it needs to be hoping people will just give up.

Nah man, solid steel still wins on clays and hard bottom.

Totally feel you on that snagging sound, it's like nails on a chalkboard (I get it with my own hair when it gets thin). Switched to a 40 too and the difference was night and day, no more wincing every time I run the clippers over the top.
