Yes, there are several options for you to buy from third-party companies that have a relationship with the prison or jail where your inmate is incarcerated. Not every facility accepts packages from all vendors so please call the facility and ask. For instance, check out these companies to see if they have an option for your inmate... Access Securepak, iCare, Mycarepack to name a few. 

They sell shower shoes in the commissary. If JPay puts money in his commissary account, he should be all set.

No, we doubt that the 'for-profit' prison package companies would take food stamps as payment.

They sell them through the commissary

Whatever amount you can afford to send is a blessing to any inmate. $100/month is a very nice gesture and will go a long way in prison for incidentals, phone time and postal expenses for letter writing

Inmates can use their money in their Inmate Account to buy commissary, add talk time to their phone, send an email and even send money home to family members.

Commissary lists for federal prisons are available on this website. Find the prison page and scroll down to "Commissary Lists" and click. There are items and prices displayed. Only the inmate can purchase items (once per week), you can add money to their inmate account for spending at the commissary.

Inmates are able to buy sneakers, work boots and a variety of socks. Click this link to see an actual commissary list with prices.

Shampoo, soap, and other toiletries are provided to the inmates. Commissary has a selection of upgraded, or brand-name products for sale if the inmate has money on their books to shop. If you were going to help, put some money on their books.

Remember that the commissary is for the 'little extras'. 75% of inmates never go to the commissary. If you are able to send something without affecting your own ability to survive while they are there, $50-100 per week and they would live like a king/queen.
