Invitations

Good morning fellow brides ,
So im sure most of you know that alot of invitation sites can be quite pricey in the end, i am the most ridiculous bargain shopper lol so i was searching around and found an app called canva. I was wondering if any of you have used this or are familiar with it? I downloaded it and played around on and created sample invites but i havent printed them, it seems as if you create your invitation and download it perhaps and print them from home or in my case since i do not have or know anyone with a printer bring it to a staples or something to be printed, i am just not entirely sure how to do it properly... if anyone has used this can you help me out please? Im not at all tech savy which people find silly because im 29 lol

fun side note about me : i didnt get my first smart phone until i was like 24 hahahaha i loved my stupid little pink flip phone ahahahahah, my mother is the one who was like you need to update yourself ahahaha
