Sales on the Brain

I have a favor to ask. I'm starting to look ahead to online holiday sales and I'm hoping to conduct a little consumer market research first. I have mentioned that I am planning a week and a half sale of awesome online, and I'm wondering what type of sale I should offer. There's a poll to the right with a few options-- if you would take a moment to tell what kind of sale you find most enticing I would greatly appreciate it! Any comments you have on what you think works or doesn't work would also be wonderful as well!

I have hosted one online sale before-- a buy one, get one last winter. It went really well, and I'm inclined to throw a repeat, but I'd like to check around first. I'm curious to see if the sale type that wins is actually the one that will save potential shoppers the most money. Would you rather have free shipping on the goods your really like, or would you rather walk away with a lot more loot? Or take a discount on your whole order?

Maybe I'll do two days of each kind ;)
