What country are you a citizen of? US?
This is what the embassy in the US says about it:
Ordinary/ Tourist Visa: This visa is issued at any Tanzanian embassy. It grants tourists/ visitors the authorization to enter the country through designated entry points on the border, through airports and harbour stations. However, a person coming from a country with no access to a Tanzanian embassy or where it is reasonably distant shall be issued a visa at the entry points in Tanzania.
You will always pay more when getting your visa in advance, even when ordering directly from the embassy in question. However, I also know that Americans do pay a higher rate than most for a visa in Tanzania. You are able to get your visa when you enter the country, as you do in other East African countries.
