i was a frequent buyer from betterworldbooks for years. at one point their value, customer service & standard of books was great but in time, i was sent more often than not books nowhere near the condition they were listed as - add to this deliveries that ALWAYS arrived later than the estimated period & a experiences with one staff member in particular who attempted to shift the blame to me (& dodge responsibility) despite my providing photographic evidence of poor condition of what was received. clearly, customers are NOT valued - only your MONEY is. on my final purchase for example, the inside covers (front & back) were stained dark yellow as if it had been peed on! yet the book was listed as 'used-good'. disgusting... suffice to say, standards got horrible & i will not be returning as a customer. to sum up, many other online used book sellers do it better & the standard of the books is also much better. if you ARE a current buyer/customer, i urge you to check the the condition of the books you receive against their book condition standards - it's clear that they do not expect you to do this based on my experiences calling them out! avoid 'betterworldbooks'....
