You need to pay more attention to whom you buy from, ask questions, and READ the feedback a seller receives.
I sold R2R tapes, and currently sell LP's on eBay. I need space, even more so now. I simply want to get them out of here to people who want them.
I offer unconditional returns or simply give a refund, you keep it. So far, none out of over 90 lps; 2 refunds for over 150 R2R tapes (1 due to PO abuse, 1 a splice by prior owner I missed).
I have streamlined the process, and yet I often wonder: why bother? The amount of work to select what to sell, photograph, edit the photos, write descriptions, find and post wiki and discogs links, answer messages, buy materials, package and ship compared to the sales price is non-sensical.
I let the market determine value. Some bring decent money, most sell for my starting price of $4.50 + $4.50 shipping. I encourage delayed combined shipping to repeat buyers. After costs and fees, I 'make' $4.00, so all that effort is for $4.00 most often.

I didn't feel competent to professionally grade: mint, very good plus, etc. so I came up with two conditions as described in my general notes.
1. Very Darn Good (no scuffs)
2. Darn Good (minor inaudible scuffs)
Also two categories: ones I clean and listen to prior to sale; and ones I visually inspect, no cleaning or listening by me.
a. ones cleaned and listened to by me, see general notes

As for 'extra' stuff in the package, you know it is to prevent movement within the package during transit, i.e. I put peanuts inside reel to reel boxes to prevent the reel movement destroying the box's corners/sides. I put 'extra' layers to prevent movement of LP's during transit. If someone pays a lot, I take the reel out of the box, pack reel and box individually and protectively in a larger, heavier, more costly package.
Donna sells and we receive a lot of purchased items on eBay. Of course 'nice' stuffing is preferable, however, if it is sanitary, and does a good protective job, thank you. Especially for low price items.
Donna, selling clothes mostly to women, always sends things beautifully wrapped. I have 2 specific size items, so I start with low cost ideally sized packaging and recycled fill, next day shipping with few exceptions.
