Is anyone going to spend actual money on incubators?

Yes, provided that I have time enough to play. I will be abroad from Friday until Tuesday. If it appears that eggs are indeed providing better Pokemon, I will spend some money.

I do have enough gym coins to go full incubator during the event, I gonna be broke after the event though. I won't buy coins until there's an other event if there's need for it.

I spend money on the game constantly and always try to have nine incubated eggs going simultaneously. As soon as one hatches, I spin stops for a replacement.

Yes. I'll run nine if the event is as rumored. At least for a few days to gauge my returns anyway.

Nope. But I've been saving my hard-earned Pokecoins for just such an occasion (not to mention my three free incubators for hitting Level 30). :)

I decided for myself, that I will not spend any more money, that I did so far, as long as Niantic doesnt approach the spoofer problem. This probably means, I will not spend anything ever again... Have around 1k coins saved up, not a lot, but I hope for some discounts in the store.

I've got about 3k in coins saved up. Definitely planning on getting one 25 pack of Lucky Eggs, I'll have to do some calculations to figure out if I'll need to get a second 25 pack of Lucky Eggs, or if I can spend the rest on incubators.
