A couple thoughts on itemized bills
In some states, not everything is subject to sales tax (for instance, in my state of Massachusetts, groceries and clothing are not taxed). This can make itemized bills that include both taxed and non-taxed items impossible to enter in one bill. A potential fix for this would be to include a check box that appears when there is something entered in the tax percent field so that the user can choose items that are not taxed. I think it would make sense to have it be an opt out system, in which every item starts with a check box indicating that it is taxed, and items can be unchecked.
In addition, it would be helpful to be able to enter a number of a given item that was bought (so there would be three fields: item, quantity, and unit price - in whatever order makes sense from a UI perspective). And the quantity field could default to 1 when blank.
Also, being able to splitting itemized items unequally would be awesome, I think, but it may make the UI too complicated to be practical.
Of course, these are all minor issues, and both can be solved by the user (for instance, for a Costco trip, the user could do two separate bills, one for taxed items and one for non-taxed items).
Great site, by the way.
We plan on tweaking itemized bills in the very near future. I think the quantity idea is a good one, along with the optional tax idea. We’ll keep these in mind when reworking the UI.

Providing quantity would help split the cost between multiple people based on how much quantity was bought for what person
The itemized bill feature is one of my favorite, but there's definitely room to improve.
In a large itemized bill, I often receive update notifications for items I'm not involved with. When I get a notification, it's also impossible to tell if I'm affected without scanning through the entire list.
A handy feature would be to show which items were updated, and also notify only those who are affected by the change.

The quantity idea is awesome.
As far as the optional tax idea I think the opt out system isn't a very good aproach. As Alex Notov mentioned sometimes there are more than one tax rate. I suggest adding another column (hidden by default) which is the tax rate. The first rate that the user adds would be considered the default one, so when the user adds another item that rate would be used. But the user would be able to change the rate for each item as he/she sees fit. Another possible alternative would be to have the default tax rated set in the profile of the user.

This is absolutely crucial. In CO, we have two sales tax rates for items: 4.0% and 2.9%. It would be awesome to be able to check the tax rate for each item or perhaps tag a group of items at a certain tax rate. The calculations in the itemized bill would then need to take that into account. The idea for entering a quantity is also absolutely awesome. I find myself doing the math in a calculator and then writing in the quantity in the item's description.

Coupons is another issue that has come up. Costco for instance shows coupons as a line item with a negative number. Being able to enter coupons this way would be very helpful.
The itemized bill in bill monk was very easy to use, there is no way to add an itemized bill between multiple people in the same way over here.
