About Search Results

YP - The Real Yellow PagesSM - helps you find the right local businesses to meet your specific needs. Search results are sorted by a combination of factors to give you a set of choices in response to your search criteria. These factors are similar to those you might use to determine which business to select from a local Yellow Pages directory, including proximity to where you are searching, expertise in the specific services or products you need, and comprehensive business information to help evaluate a business's suitability for you. “Preferred” listings, or those with featured website buttons, indicate YP advertisers who directly provide information about their businesses to help consumers make more informed buying decisions. YP advertisers receive higher placement in the default ordering of search results and may appear in sponsored listings on the top, side, or bottom of the search results page.

Let's just say that I avoid going into the post office as much as possible. Lines are long, clerks are slow and not very friendly. But my concern is with the letter carriers delivering to our house. We had a wonderful lady for a long time whom I didn't get to say 'goodbye' to. When her replacement began I asked if our previous lady was ok. She mumbled a response that I could not understand. I wanted to just say 'welcome' but she was already driving off. She drove way too fast for an area with 25 mph. She'd obviously hadn't got her deliveries right because we'd see her zipping back down the same street on numerous days. All of our day's mail would end up in someone else's mailbox. People on our same street would walk our mail over later that day or the next. We have done the same for them. This was beyond just ending up in a next door neighbor's box. Then we had a male carrier on weekends who did a fine job. Now we have another carrier who is not suited for this job. We are missing 4 items (that we know of). All are thin, business postcards, glossy material like company newsletters and probably got stuck to other mail, just not ours. All my husband's magazines arrive not just bent to fit in our box but with actual creases. Neighbors have complained about the same problem. She stops her mail truck blocking traffic and sits with no rear lights flashing so we don't know if we should go around her or wait til she moves. The misplaced mail is an ongoing problem. I can understand when it's addressed to another street with the same house number, but today's mail was not like that. I don't even know where the street is. I'll just put it back in my mailbox for the mail carrier to pick up tomorrow. We would appreciate these inexperienced carriers to be more courteous, follow the rules of the road and get a pair of reading glasses. We live in the Lake St Louis area.

The lady (I think her name is Celeste,) who handles walkin's with purchase of stamps and helps with packaging, was really a great help to me. I had been in there previously to check the packaging sizes and I couldn't find one I could use, Celeste told me to bring in the package and she would help me. Today, I took it in and she took care of it for me.
