Help Samara buy blood for her surgery!

My Friend Samara has stones in her gallbladder and has been in pain for over a month now, she's in the hospital at the moment and her surgery cannot proceed until we have enough money to pay for the blood transfusions, she's a B+ type which is really rare Around here, we haven't been able to find any donors of blood for her type, the last option is to pay for the blood from the blood bank but the amount we need to pay is of more than one months salary for her, she doesn't have any family in this city and what we could raise by ourselves hasn't been enough, we are now recurring to this method to maybe be able to raise enough money before Monday when her surgery is due.

Please help us! With as little or as much as you can is truly appreciated from the bottom of our hearts!!!
