I bought about 30 or 40 rolls of solder about 1970. Prices are always going up I figured some day a roll of solder will be 10 times more expensive if I buy several it will save me money over the next 50 years. I don't remember what a roll of solder costs in 1970 but I do remember minimum wage was 90¢ & ok pay then was $3.50 per hour. I checked the price of solder last week only thing I can find is lead free plumbing solder 1 lb roll $10 per plus $1 sales tax. I still have 1 roll of antique solder left I might need to buy some one day. Is electronic solder lead free now? How much does it cost? Who sells it?
