Leaves have started here too. Normally at this time of year there is a gust of wind off the Atlantic and they are all on the floor but it's been still for weeks now. The colours are very New England-like at the moment - I just hope it lasts a little longer.
If it's a big box store they're used to people showing up with hybrid cars wanting to get some plywood home and will usually cut for free. If it's a lumber yard they're used to people showing up with trucks and trailers and buying a ton of wood and will probably charge you. Change sucks but I wouldn't sweat the $10 especially if you've always liked the place and their wood in the past. Crap, if some people actually figured the numbers, it cost them $12 to cut a $2 2x4 "dead nuts on" with their Kapex.
