Some great advice from Leslie, and agree, make sure you are still price competitive and stay close to DQ as they will no doubt be rolling out a domestic marketing campaign soon. If you are not already a member of this group on FB might be worth joining, has over 800 members ow and you might even be able to offer some industry rates to fellow industry people for when restrictions are lifted.
You might like to offer a free bottle of Central Otago Pinot Noir to sweeten the deal on your website, possibly run a competition on FB to win a free night to grow awareness of your product and any deals you may have. this site has just been launched and is about to get a lot of PR so you might like to do something for these guys who are supporting health care workers with great deals to say thank you
Best of luck.
