Flyers or Postcards?

I have decided that I would like to change our idea of creating flyers to creating postcards instead. I think that postcards look a lot more professional than flyers. Flyers tend to be created using paper which will be very flimsy and look a bit cheap. Although, using postcards, this would look a lot more professional and would help to reflect our clients business, especially as she is looking to aim her art work to more corporate audiences.

I have looked at different websites where you can create postcards and where businesses will print off the postcards you have designed and send you them. I have been looking at the different prices and what they range from.

This is the first website I looked at which is called Moo. This website allows you to use some of Moo's designs or you can create your own designs on this website. I would like the postcards to be doubled sided as I think that this will look a lot better. This costs £6.59 for ten postcards which works out about 66p per postcard. 

This is from the Vistaprint website which allows to create and design your own postcards. I would like to use A6 size. The cost for ten postcards is £2.99 which works out about 30p each. Although, to have the postcards double sided will be about £4.48 which works out about 40p each which is a lot better than above.

This is from Printed.com which I think looks like very good prices. Although, this is probably due to the fact that the postcard is only single sided. For 50 postcards it costs £12.83. This works out about 25p each - although they are not double sided. 

After conducting this research I have decided that the best website to print out the postcards with would be the Vistaprint website. I think that they are a reliable business and also are good for the price that you are paying.
