on offer

1. Available, as for purchase or acquisition. We have a wide range of craft beers on offer, including some from our own in-house microbrewery. There's a car on offer down the road for only $2,000.

2. Offered at a discounted price for a certain, limited period of time. Primarily heard in UK, Ireland. This weekend only, we've got a huge range of appliance and electronics on offer. I saw in the paper that the grocery store has slow cookers on offer—maybe we should go pick one up.
