Great work idolcarrie22.
We can report a couple sellouts.

The Canada concerts have been leading the pack in sales. Carrie's 10/6 concert in London Ontario had no tickets available last Saturday. Carrie's 11/24 concert in Lethbridge Alberta also has no tickets available. Also close to selling out are Carrie's 10/11 concert in Moncton and her 10/12 concert in Halifax.
There are a few concerts on the US side I'm watching because I think they could sell out pretty soon if they got a little push (Detroit and Chattanooga are 2 of them). But the concerts are a long way off and that push might not come until a month or a month and a half before the shows. If Carrie does some TV appearances that mention her upcoming tour this summer or the local radio stations do some advertising that could be the push needed.
Usually with arena shows you can tell a lot about how sales are going to go from how the 1st 24 hours on sale go. IMO even though there weren't any instant sellouts, this leg of the CR tour is selling very consistently and I think it's mostly off to a better start than the June leg of the CR tour and there's a lot more time to sell tickets than there was for the June concerts. I agree with idolcarrie 22: sales are looking good!
