At Garden's grocery store in Ramallah, Dalia al-Khatib hands out fliers and showcases Palestinian goods for Intajuna (our products), one of many campaigns asking Palestinians to avoid Israeli products.
But across town, an all-Palestinian crew of labourers heads home after a day of work on the nearby Jewish settlement of Adam, like some 30,000 other Palestinians who help build settlements in the Israeli-occupied West Bank.
The contrast illustrates a Palestinian dilemma. After 40 years of occupation, their economy is tied to Israel's, so attempts to reduce its dependence clash with hard realities.
Palestinians use the Israeli shekel as currency. From cars to shampoo, countless goods come from or via Israel. Most packaged foods and household products have a foreign or Palestinian counterpart, but fruit and vegetable vendors say they would be out of business without Israel, where most produce is grown.
Mocking the boycott, one vendor plucks the shirt he is wearing. "Even if this isn't Israeli, it probably has to be shipped through Israel. So what am I supposed to do?"
Calls for boycott started as far back as 2004, without much result. But that changed after Israel's Gaza offensive last January, says Mustafa Barghouti, a member of the Palestinian Legislative Council and a boycott advocate.
Boycotting, he says, is a great way to oppose Israeli policies non-violently. And it can help reduce Palestinians' dependence on the Israeli economy.
His outlook highlights a new tactic in many local campaigns, which now focus on developing the weak Palestinian economy.
"This isn't actually a boycott of Israeli products," says Mr al-Khatib."This is about supporting Palestinian goods."
The new trend in Palestinian grassroot movements seems, ironically, to fit with Israeli Prime Minister Benjamin Netanyahu's "economic peace" plan, which calls for Israeli implemented measures to develop the West Bank economy.
This has begun with relaxation of Israeli army restrictions on movement and the planned revival of mothballed foreign projects.
The US and Britain recently acknowledged the positive impact of Israel's removal of checkpoints on the commercial life of West Bank cities such as Nablus.
Though Intajuna showcases are popping up in more Ramallah grocery stores, Israeli goods remain on the shelves, not least since many Palestinians are wary of their own national products, especially dairy, saying they fear spoiled goods.
Mr Al-Khatib says Intajuna carefully screens goods.
According to many grocers, the campaign has increased shopper interest in Palestinian goods. But in spite of that, only a few noted a real change in buying patterns.
What most activists agree on, however, is a complete boycott of products from Israel settlements, which are built on West Bank land that Palestinians need, to create a viable state under a comprehensive peace deal with Israel.
Settlements have been growing since Israel captured the land in the 1967 Middle East War. A half million Jews now live in the West Bank and Arab East Jerusalem, among 2.5 million Palestinians.
Ruled illegal under international law, the settlements are seen by major powers as a serious obstacle to a peace agreement.
