I think at market price it was around a 27 loss per high alch, about a month ago, it shouldn't be much different now.
make your own emerald bracelets - not sure if it still works alot of bracelets and some pouches work well
well the only problem with longs is that u can only buy 100 every 4 hours. Thats why i have tons of offers in there for yew longs waiting to be bought. so when i want to alch, they will be there.
