Gifts Cheats & Tricks
Before you give any gifts, right click on the 'gifts' tab on top of the game and select 'open link in new browser'. This will open the gift giving screen in a new tab in your browser.
Repeat this a number of time (as many as you have time for). Once you have all your tabs with the gift giving page open, go back to every single one and select the gift you want to give. Do this for every single tab without confirming the selection. Once you have done this for every single tab, go back again and confirm on each page, selecting who you want to send the gift to.
Again, do not confirm the sending of the gift on this page. Do this in every tab again, and when you go back to your first tab, you should be able to confirm the gift and send it from each of your open tabs. This way you can send unlimited gifts to your friends, or if you'd like to receive unlimited gifts, create an alternate gifting account that can send you an abundance of any gift you would like.
