I have my local comic shop save back a few comics for me each month because I travel for my job and can't make it there frequently. Also, they give me a decent discount on the one's I have held. I show up on Wednesday and they are sold out of CAP #25 so, I don't get my issue. This has happened a few times. The last time it happened I told the owner "If nothing else, make sure I get my Cap comic". What the shop does is set out new comics for the general public and whatever comics don't sell that day go into the saved bin. There's been a few times where they were sold out of the comic I had saved but they held back comics for me that I could care less about. I'm a nice guy; if it looked interesting enough I would go ahead and buy it. I had a subscription for years. But, I like going to this shop now and again so, I thought I might as well give him more business. Is this common practice? The owner's a nice guy but it seems disrespectful to me.
I say look for a new shop if you can. My store orders issues specifically for their pull list client, so you never have to worry about not getting an issue on your list.
But I could see a small store in a small town not having the budget to do this.
