After reviewing your request, the publisher may decide to charge you a fee to use the material you have asked to use. This fee is to reuse the copyrighted material, it is not a fee to use PLSclear.
Prices and quotes are determined by the publisher. Therefore the PLSclear help desk team are unable to provide you with guidance or estimates for your request.
If you wish to query or negotiate a licence fee, leave a comment on your request as this goes directly to the publisher for consideration.
