In the pricing discussion (hey stop people if you've heard that before) I just want to interject: It pays to ingratiate yourself to the people who work there. Talk to them, smile, say hello every time you go in, learn their names, say "Hi, [insert name here]" and don't be a scowling jerk like some of the customers I'm sure you've seen. Take them donuts! Whatever.
This paid off for me recently. just a small thing, but I knew it was a reward for "paying it forward."
Rhoda, who works at my local SA, actually encourages me to come in and buy stuff to flip. She is so friendly to me now that she suggests things for me and hopes I find things ahead of others. They're living month to month on the store rental, and she appreciates my loyalty and understands that regulars like me are helping them out.
They're also pricing some things higher now in hopes of making the rent.
I walk in last week, find a Polo SC in great shape, it's priced $9.99, which is 2x-3x the usual. She looks around when ringing me up. It's half-price day for every tag color except the one on this particular jacket...and says "Honey, this too expensive." Rings it in at half.
Rhoda rules. Small victory, but that rule "Don't be an ass" will eventually pay off for you, somehow.
