Don't you hate it when you buy something and it doesn't work? All that hassle of having to go back to the shop with the receipt, give it to the cashier, wait around for a while staring into the abyss or making awful small talk, before leaving with a refund or replacement. And for what? Because the factory didn't check before that it didn't work.
We could really do without giving broken products.
So please, please, please can you just double check for any spelling mistakes, or if it's a PowerPoint just make sure it works properly.
It'll only take a couple of minutes and will save us a huge headache. More mistakes from more uploads=more time for us to check, and more likelihood something will slip through that'll eventually be returned.
