Default bricks

Hi, I'm building a retaining wall in my garden and I've seen these
bricks on ebay
http://cgi.ebay.co.uk/ws/eBayISAPI.d...tem=5966785622

I was wondering if anyone here had any comment about the white marks on
the bricks. Is this effloresence? Do all bricks do this or is this a
sign that these are not of low salt content thus I would need to use
sulphate resisting cement? Does the white go away once washed off?

My other easiest option is just going to my local wickes but I'm not
really sure of the rating of their bricks either other than they say
they come with a "frost guarantee".

Am I worrying too much?
