Now that my son has accepted that his "Ba" (bottle) is truly a thing of the past, what should I do with his bottles? Part of me wants to donate them (I even have unused nipples in packages) to a local shelter / food bank, but of course we all now know that clear polycarbonate bottles probably leach bisphenol-A into the milk. (saccade, I should have listened to you!!)
I'm very conflicted about this. Can you help me make the most ethical choice? [more inside]

I need some really REALLY basic spreadsheet help. I've been given the task of creating a spreadsheet that will work out for us several things - how many orders we need in total and per week, how much revenue this will bring, etc. I've got most of it worked out, but I can't for the life of me how to work out percentages.
Yes, I did Google this before asking. :D [more inside]

I've got an Excel spreadsheet with numbers ranging from 2,000 to 600,000. I want Excel to look at each cell and essentially categorize all of those into five categories in a new column. If the value is less than 10,000, I want Excel to give it a 1, if the value is between 10,000 and 50,000 I want it to be 2, if the value is between 50,000 and 100,000, I want it to return 3, if it's between 100,000 and 500,000, I want a 4, and if it's above 500,000, I want a 5.
I tried the IF function, but I can't figure out how to a) make it recognize multiple variables, and b) I don't know how to tell it to look for numbers within a range. The Excel help section about arrays and lookups is fairly mystifying. Anyone got an idea?
(I know I could sort the data and do this manually, but I'd like to learn how to do this Excel's way.) Thank you!

[BottleFeedingFilter] I'm expecting our first child in July. Although my preference is to breast feed exclusively, for medical reasons that simply may not be possible. Therefore, I'm trying to mentally prepare myself for exclusively bottle feeding, and then anything else that happens will be a welcome bonus. What equipment do I really
need in order to bottle feed, what is just "nice to have", and what is a waste of money?

ExcelFilter: I need help creating a pie chart as a separate worksheet in Excel that counts how often values appear in a column and creates a pie graph based on that data. I'm stumped, I'm not using the right Google terms, and my company's help desk couldn't guide me through the process, either. (That sounds awkward, so I describe it more comprehensibly inside.)

NotQuitePepsiBlueFilter: Vacationing in Europe, I was surprised and pleased by the flavor of Coca-Cola Light, which is not made with the same formula as the rather dire-tasting American Diet Coke. The drink tastes pretty much the same as Coke's new C2, but instead of that soda's bizarre half-sugar, half-sweetener compromise, the European Coke Light does it with no sugar or calories. Why they don't sell this stuff in America is truly beyond me.
Thing is, I'd like to import some -- and while imports of other (slightly stiffer) European beverages are common, I can't find anywhere locally or on Google who will sell it to Americans. Then again, my EU language skills are lacking. Anywhere I can have a 12-pack of this stuff shipped to me?
