Hey Guys

I'm setting up a greeting cards business.

I've got all my designs but haven't printed them yet.

Should I approach Retailers (Clintons, Card Factory, Tescos) before I have any hard sales?

I mean, should I sell on my website, target local shops first, and then approach the major card retailers? This way there's evidence that the cards sell.

The reason I haven't printed them yet, is because if retailers take orders, they'd require barcodes on them. I do want to add barcodes if its not necessary at present.

Basically all I'm asking is, whats next for me?
