A while ago I discovered that I needed outer envelopes for my Vistaprint invitations. Since then, I have been searching for great deals on envelopes.
First, if you are using Vistaprint invitations and their envelopes as inner envelopes, then you need a size A8 envelope for your outer envelope.
Here is the breakdown of sizes:
Vista Print Invitations: 5" x 7" (actually 4.61" x 7.17")
Vista Print Envelopes: 4.75" x 7.50" (slightly bigger than invitation - perfect for inner envelope)
A8 Envelopes: 5.50" x 8.125" (next size up from inner envelopes - perfect for outer envelopes)
First things first, you CANNOT find A8 envelopes anywhere in stores. The closest thing that you will find in stores are A9 envelopes (5.75" x 8.75"). And stores only sell them in white. In my opinion, these envelopes are just too big.
Just in case you are interested in the A9 envelopes here is what I have found. Craft stores don't sell them (I checked A.C. Moore, Michaels, and Hobby Lobby). You can find the A9 envelopes at office supply stores. I found them at Office Max ($16.99/100ct.) and Staples ($13.99/100ct.)
Returning to the search for A8 envelopes - your only option is to buy them online. I still haven't ordered, but here are my top three sites..
1) envelopesexpress.com: This is my current favorite. Sample are completely free (including shipping). This is the only site that I have found with this offer. They also have a large variety of colors.
Cost: $42.30/100ct + $0 shipping = $42.30
2) envelopemall.com: Samples cost $1.50 per envelope with free shipping. However, shipping on a regular order is not free. Also, they have a more limited color selection unless you go with metallic envelopes (these are NOT good for shipping, they confuse the machines a the post office).
Cost: $21.95/100ct +$10.01 shipping = $31.95
3) jampaper.com: Samples are free plus $3.25 shipping. They have a large variety of colors. Also, when I signed up for the email, I got a coupon for 15% off my first purchase.
Cost: $28/100ct + $13.09 shipping = $44.74
