From time to time l have used Lloyds Pharmacy online for stocking up on our little blue friends (not often, though).
I had a birthday recently and on the day got an email from them offering a 20% discount as a birthday present. I only previously used them occasionally as they are a bit pricey, but l thought with a 20% cut they may be a reasonable proposition.
Anyway logged in, had a look, and 8 x 100mg generic sildenafil was priced at £35 - so with the discount, only £28 for the 8 tabs - £3.50 each which compares well with other online suppliers, as well as ASDA. l don't recall what l paid last time but l'm pretty sure it was a fair bit more - so seems they have cut their prices!
