Googled this site and another. But don't know how to view the free shipping code or maybe these sites are attracting ads only.
Would someone know if Farmers have free shipping code? Only looking for some small items under $50

My own experience of those type of sites is that they are almost always useless for codes - they are just serving ads and want you to click to they get paid.
There might be exceptions, and I would be delighted to find a similar site that actually provided useful coupons / codes reliably, but I remain sceptical.
As for Farmers, I don't shop there unless there is a stunningly good deal for far lower than anywhere else, since they charge for click and collect, and quite a bit for delivery, so they'd have to cover those charges by selling for a lot less to cover my risk of them being out of stock if I am going to look to buy in store. There are no free lunches and, for me at least, Farmers have to cover the costs they pass on to me as a customer, else I'll just go elsewhere.
