Speculation has been mounting that Google will introduce a model of its tablet with more internal storage, following the release of 8GB and 16GB versions in July.
The Staples Advantage website in the US, which is aimed at business users, has now listed the Google Nexus 7 32GB tablet, priced at a very competitive $248.27 (around £150), reports The Next Web.
The site stated the estimated delivery date of the tablet as tomorrow (October 18).
UK retailer Argos has also leaked the product in its online Christmas gift guide, revealing that the tablet will cost £199.99 in the UK.
This price would make the 32GB Nexus 7 slightly cheaper than the 16GB version, suggesting that Google will also announce a price cut across the range.
According to the leaked listings, the specifications for the 32GB Nexus 7 remain the same, it is just the storage that has increased.
Neither Google nor ASUS, which makes the Nexus 7, have commented on the report.
Amazon's Kindle Fire HD will be available in a 32GB version this autumn, and Apple is expected to announce a new iPad Mini device next week. Google is therefore possibly looking to ensure momentum with its own small screen tablet ahead of rival devices.
