The vouchers, which have been individually posted out to all season ticket holders, should arrive by Friday morning in time for the top of the table clash on Saturday against London Irish on Saturday and are valid until the beginning of May.
Head of Sales and Marketing Pete Grzonka said: "This is a great way of adding value back to our most important members and we are delighted that Rugbytech, our official kit supplier who manages the stadium shop, have decided to get involved. We have 8000 season ticket holders so a promotion of this level represents a massive investment from the club and one of its partners.
"We have recently reduced ticket prices for match by match attendees for certain games in an effort to alleviate the burden of a congested fixture list and also to recognise the economic environment. We want to see a full stadium and the discounts have been introduced to help Gloucester Rugby supporters' cash flow.
"At the same time, there has been a steady increase in the number of our season ticket holders over the past few seasons and we are really keen to maintain and build on this incredible level of support.
"We were very careful that any of our promotions do not undercut the discount season ticket holders get on their match attendances, but we have been looking at ways of recognising the fact our season ticket holders, who have paid up front for their tickets, are guaranteed additional value too.
"It is our belief to continually look into ways of applying the same cash flow alleviating principles to our season ticket package for next year and are in the process of finalising details of a payment plan which will be released at a later date."
