I won't spend more than $20 a season so it's been taking me forever to complete the series. I found season 5 for $16 so I snagged it.

If anyone finds season 6 for around $20 (including shipping), please give me a shout. Then my series will be complete.

Thanks

Note the used one for 19.99 plus 3.99 ship:

That is over my $20 limit, but thanks anyway.

The strangest thing happened today. A credit card company sent me a $25 refund in the mail. I have not bought anything from this company in over 2 years.

I decided to buy the $19.99 copy that Stevea suggested. Collection complete.
