It is not so much a mistake as the weird way direct storefronts show prices.
The reseller prices are from $6.95, the retail price of third level .in is 7.89, and directi shows the lowest cost domain price at the header even though prices are different for different extenstions. It was worse when that was .info for like $2.50.
I adjusted the .com to match so it is less confusing. I complained a bit to directi about that before but I don't think they want to do anything about it.
