I try to be as frugal as possible. I would say less than $3 a page...and that's mainly due to the 3D stickers I use.
The most I have even spent - that I know of - would be around $10 a page. That's due to 2 sets of Jolee's wedding stickers.
That's kind of a hard one to figure out. I'm like Wendy and try to be as frugal as possible and stretch those supplies! I would say on average around the $3 range, too.
I guess that I have never calculated how much I spend on an actual page. It depends on the embellishments I guess. I usually am pretty frugal when purchasing those.
I would say an average is $3-5. I wouldn't say I am frugal but I do look for a good value plus I have soooooo much stuff. I used to get 40% off at Archivers so I added to my collection of supplies. I did sign up for a swap once and they set the price of $10 a page as a minimum...the swap didn't go because no one wanted to spend that much.
