Buying methanol is not so easy. It is not available everywhere due to its toxic matter. In case you want to buy it, you can inquire it at your nearest gas station. The gas station people will recommend you some names or if they have methanol available, they will gladly sell it to you. A gas station storing methanol is very rare. You can also look in the phone directory and look for people who sell chemicals to industries in huge quantities. The only catch that might be is that you might have to buy methanol in huge quantities. Methanol is basically used in cars especially racing cars such as Formula 1 cars, rally cars and monster trucks. It is also very widely used in aeroplanes and railway engines. A lot of care has to be taken when dealing with methanol as it is a harmful substance and can cause serious injuries to you body.
If you don't mind having 97%ethanol, methylated spirits(the 3% is why its called methylated). That would be the only normal way of getting some, do you mind if I ask why.
