Yes, it's a bit awkward to find the first time. Yes, some of the things are a bit overpriced, but for the most part it is the new items because you are comparing them to traditional goodwill prices. I agree that there aren't a lot of the $1.00 items. That's not what they are going for. They are going for a more upscale version to attract a new sect of buyer.
The system they have in place is if it has a colored tag, it is considered a donated item and is eligible for all the discounts and coupons and what not (and yes, they do have 50% off every other Saturday on donated merchandise only.)
Just like with ANY trip to ANY thrift store, you may not find anything or you may find one of those diamonds in the rough. My parents got a two piece tiered genuine Thomasville furniture hutch and buffet table for $120 and I've gotten multiple pictures, frames and knick knacks for SUPER cheap!
The new furniture has a floor model and that is what is in the store but you can also custom order the furniture in different colors as well and have it delivered to your house. Plus, since it's goodwill, there is no sales tax so the price you see is what you pay. The man and I were looking into a couple of different options and asked some questions, so that's how I learned this stuff.
We also learned that this store gets some of the first picks at donated furniture so they can offer some of the better pieces and they won't sell clothing or shoes at that location so it doesn't have that musty smell that some do.
Overall, I've taken several friends with me and referred several others and as long as you don't expect to walk into a traditional goodwill, you'll be pleasantly surprised!
