I enjoy the simplicity but am annoyed that you can't use certain features without paying a higher price. $80/year is pretty high for a basic subscription.

I love how easy PDFfiller is to use, and with all the how to do's no one should ever run into a problem they can't overcome on there own. As well the membership cost is great. Thank you so much for this great program.

I have used PDF filler often to complete PDF forms. The program is very user friendly. I love it! I love the ease of use it creates when completing documents. It takes the hassle out of completing some of the complicated documents. I really don't have any negative feedback about the software. Sometimes the text of the document overlaps and I have not figured out how to avoid that from happening.

It was fast, easy and extremely self explanatory. I actually signed up for it because it was worth it. I recommend it to anyone who needs access to documents quickly. There was also a plethora of different forms to choose from.

Scary since I am using lots of numbers for an IRS form and I've forgotten which email I've used and what my password is and I have to redo this form. I need training.

I am very pleased with the program but I was upset to find out that I could not print or save unless I signed up for your trial period. But this was just what I needed, when I needed it. I would recomend to my friends.

Forever Stamps were first introduced in 2007 by the USPS. This also means that should you want to mail a letter next year or even after 4 years, your Forever Stamp will still be valid and useful. So, if your old stamps are Forever Stamps, you can use them for postage without any issues.
Most people can relate to buying a book of stamps only to have the price of stamps change and then not being able to easily use the stamps. Old, unused postage stamps don't expire and can continue to be used, although additional postage might be necessary.
You can keep using them, if you take the monetary value of the stamps printed on them, use a combination that meets or exceeds the current cost of mailing that item. Let's say you have an old 39 cent stamps, this can be used to mail a postcard (current postage required 34 cents).
Many collectors have sheets or smaller quantities of unused stamps issued years ago, and if they have no premium value, the collector might use them for postage on letters and parcels.
All postage stamps issued by the United States since 1860 are valid for postage from any point in the United States or from any other place where U.S. Mail service operates. You may use any Denomination stamp(s) to equal the total postage affixed.
Affix 1 Forever Stamp (costs $0.49) or 1 First Class Letter Stamp in the top right corner of an envelope to send a letter. Forever Stamps are best for mailing 1-ounce letters (of standard size) within the U.S. Affix more than 1 Forever Stamp if the letter weighs over 1 ounce.
