Raw eggs keep a lot longer. Interestingly, hard-boiled eggs do not keep nearly as long as raw eggs, which can last three to five weeks in the refrigerator. There is a good reason for this. When a hen lays an egg, it puts a naturally protective coating on the outside of the shell.
As of June 2014, the United States Postal Service states that the cost to send a standard sized postcard is 34 cents. At this rate, the postcard can be 6 inches long, 4 1/4 inches high and 0.16 inches thick.
After that, for every multiple of 50 postcards (sent), you will be allowed to send one more. 1  If you have sent between 0 and 4 postcards, you can send 5 postcards. 2  If you have sent between 5 and 14 postcards, you can send 6 postcards. 3  If you have sent between 15 and 24 postcards, you can send 7 postcards.
