The limited product range offered by GPI was a source of frustration for me as a product manager working in the manufacturing business. Even though they had a decent selection of poly and plastic packaging bags as well as shipping supplies, they were lacking in industrial and scientific supplies. I had hoped to find more specialized products to meet the requirements of my business, but I was forced to look in other places. In addition to this, the website's structure could be improved to make it more user-friendly, and the products could use some reorganization. In general, while GPI might be an adequate choice for some fundamental packaging requirements, it is not a good choice for more complex industrial requirements.
