How much would you pay for this scrapbook kit?

About $5, maybe, depending on the quality, brand name, and how much I really liked it. You can find some small coordinating kits, such as the one you described above, for about $5 at Joanns.com in multiple themes, such as a summer one like this one:

As described in that specific set, it contains enough supplies for (6) layouts. It includes:

(6) 12''x12'' acid & lignin free patterned papers,

(82) cardstock alphabet stickers,

(38) cardstock punch-outs,

(2) chipboard punch-outs &

(13) raw chipboard accents

for $4.99 and you get much more then just die cut embellishments. I have bought some of these kits of different themes and loved them. Hope this helps!
