Mail SPAM?

Today I got 4 of these in the mail...I usually get 2-3 a week, but these all arrived together. This is not the first time I've had 4 at once either. I buy from them once a year only (for Romania supplies) and that is all. Pretty sure the hundreds of magazines they send each year cost almost as much as I spent (it wasn't much) I assume it pays off in the end, but really? How many different covers can you have for the same products featured in different ways? I'm not a marketing genius, but this seems off.

Same stuff in each one, as always.
