I'm sorry Vata, but I am still not convinced, but, it's your money and your collection; it's your call as to want you want to do with it.
I'm only stating my opinion on the matter, I'm not trying to persuade anybody to do as I do.
But, I will admit, I do have a certain amount of vanity regarding my anime collection, it's petty on my part yes, but that's just me. I don't really have any other vices in my life (I don't drink or smoke or consume large quantities of food) and my hobbies (bass) can at times get pricy, but it's how I can afford the anime I buy - aside from bass(strings mostly - every few months), anime(blurays and wall scrolls) and living costs (the car mostly - insurance, gas, payments) I don't spend too much money, I mostly save it or try to invest it.
I will admit though, I am something of a cheapskate(it's how one can save money), I usually bounce between Amazon.ca, Amazon.com and rightstuf for my anime bluray shopping - I consider the face price of the product, but more importantly; I take into account shipping fees that may be incurred ordering stateside(rightstuf and Amazon.com) and there are also customs fees and the possibility of the shipment being delayed - like my last order. Sometimes, even though Amazon.ca has a higher price, it's cheaper than ordering from the state sites(due to extra shipping and customs costs) - and sometimes, although rare, Amazon.ca is cheaper or the same price, as was the case with Heaven's Lost Property, Berserk or the Inuyasha sets.
But, as I said, I am cheap; I did enjoy Puella Magi Madoka Magica, but I'm unwilling to pay the $120 for the total set (3 sets at $40 apiece) I can't justify spending that much on an anime I thought was good, but didn't blow my skirt up. I'd also like to have Sailor Moon, I didn't think it was great, but it was a fun watch, but I just simply will not pay an outrageous amount for it or buy a bootleg, for me it's just not an option.
But that's what I choose to do with my money and my collection - and I'm not implying I'm a better person for it, it's just how I do things.
