ok   great   thanks   so all we need is the paper work showing we purchased mu;ti day permit     thanks again

No other way to buy them. Carry paper work with you that you purchased it. Police can checkthe data base to verify it too. Multi day ones you can print them and carry it with you, but full season they mail it, but still valid from day you bought it with paper work. 👌

do you get some type of receipt when you purchase online that you can use if permit does not arrive on time ?

concerned they wont reach us before planned trip   wanting to start around the 25th of January  how fast is their turn around ?

Online on OFSC website is only place at moment to buy them.
