My PC is getting very dusty inside and I just ran out of compressed air. I need to a good place to buy cans of the stuff, mainly a cheap price, but an effective product.
Staples usually has a deal in store where it's B1G1 of two packs for $14.99. In other words, you'd be getting 4 cans, and they're decently sized (10 oz).
I ran out of my costco pack a few weeks ago acutally. I didnt have time to go to Costco again, so I just picked up a two pack at Target for 6.99. Its not the cheapest option, since I believe I got a 3 pack at Costco for 8, but the Target cans are good enough.
Damn, I spent like $15 on a 3-pack (10 oz. each) at Office Depot the other day. I thought it was a decent deal because online prices are like $8 per can
Now that I think about it, that 3 pack from Costco lasted me about 4 years. The only time you ever do use it is if you notice the dust yourself, or if your computer is running too hot/ too loudly. Unless you plan to do a weekly cleaning, even two cans should last you a while.
