Great service from Optibac
Great service from Optibac. I ordered the Travel Biotics for an upcoming holiday abroad and got them on offer. Free delivery & they arrived within two days of me ordering!
I also purchased these last year for an all inclusive holiday to Cape Verde. Myself & my husband had no tummy issues at all so I purchased again for our next holiday.
