Another Catholic school parent here:
Catalog sale - This always starts out the year. I only buy a small amount for myself and never sell to anyone else. (around $30)
Coupon book sale - It's like an Entertainment book (can't remember it's name now). I buy one for myself and that's it. ($20)
Candy bar sale - Mandatory that we buy a case. I buy the case, take out a few bars and bring the rest to work and hand out. My co-workers love this sale.

($48)
Spirit Wear Sale - depends on the merchandise they are offering. I hooked them up with the company and they give us really good prices. So I vary year-by-year. This year I ordered more but last year I only bought one t-shirt. ($100 this year).
Yankee Candle Sale - I do not support this. It helps to pay for the school field trips but I would rather give them an extra $10 for the trip then to buy another candle! I don't burn them anyway.
Easter Candy Sale - Self-explanatory. I only buy for us and do not sell to anyone else. ($40)
50/50 Raffle - This is mandatory. Need to sell $40 worth of tickets. I usually sell about $10 to family and buy the rest myself. ($30)
Gift Cards - Sold monthly. I don't support this. Every time I want to do it for the holidays I either miss the deadline or don't have the cash handy by the deadline. I usually end up buying my gift cards at the last possible minute because I really look for gifts instead of the cards.
Basket Auction - Tricky Tray, Chinese Auction - all the same thing. I work on/donate heavily to this event. The whole family ends up helping with this with either moving the baskets from place to place, soliciting donations or just help cleaning up the room as we go along. We put together some pretty impressive baskets and it's the biggest fund raiser of the year. We make over $30,000 on this event. I usually end up donating merchandise with a value of around $500. Then on the night of the event you need a babysitter as children cannot attend. I shell out money to help offset the cost of the food ($50) and then we participate in the auction itself by buying tickets, etc. ($200). So I easily drop $750 on this event. Wow!!! I just added that up!
And on top of all that, we pay a "fundraising fee" of $300 every year. I'm not quite sure what that fee is for as I do plenty of fundraising.
I hate fundraising!!!!! Oh yeah, and the priest threatened to start bingo up again. I heard this in church for the first time and went

. I turned to DD and told her that I had no time in my life for bingo. We had already spent 12 hours at the school that weekend working on basket auction stuff and this was only Sunday morning. We were headed back to the school to do more. She innocently told me that others would help out. I just asked "Like who?"

Unfortunately, it's the same 20 families that work all the events.
Oh yeah and book fair twice a year and Christmas shop at the holidays. Okay, now I have to go back to work and earn more money.
Please...someone else post that has more fundraisers than me. I really need to know I'm not alone!!!
