Here are some details:
1999 version of Power Glide Children's Spanish I
(It looks like they sell the three levels now as a set for $120 at CBD)
This is ( I believe) level 1 and comes with 4 cassette tapes
It is still in the original packaging and in very good condition. There are two student books (which are not written in) , 1 parent guide and 4 cassette tapes. The tapes all work but 3 of them have become discolored from age.
I was thinking $30 for the set plus shipping. I can do PayPal. Let me know what you think.
Thanks for your interest.
