I'm going to Frank N Sons Saturday to pick up supplies. I've been there a couple of times and aside from the Lincecum fans (
) I like it. For wax I tried playing two vendors off one another and it worked. I wasn't desperate to buy so that helped. Smartphones are king here because you can quickly check values and see if they're trying to take advantage. Supplies are plentiful and the signed memorabilia, while high in price, is still great to look at.
There's also Jimmy's USA - Rob is great with prices
I think in Anaheim there was Tiple J's or JJJ Cardshop. Last time I visited them they had great prices just no singles.
